Guys...

Hope someone can help on this one...basically finished all the wiring on the car now ready for the centre section install.....just trying to finish up the odd jobs one of which is finalizing the ford escort (MK4) stalks. I've figured everything out with the exception of how to get the bloody park function operating on the wiper....any of you clever peeps that can help out?? Really appreciate any words of wisdom from those that have already done this mod.....

Thanks, Simon

PS - I'll post a few progress update pics in the next few days or so.....

I'm not that great at electrics, but looking at my diagram, it looks like the green wire going to terminal 53e on the motor is parking and I have the violet/black wire piggy backed to this.

All the Fords I have ever had, the wiper motor has a built in switching unit.

When you engage the wiper with the stalk switch, you send power direct to the motor. When you switch the stalk back off, the power to the motor comes via the switch inside the motor unit. That motor unit switch is open (off) when the wiper is parked, and closed (on) at all other times when the motor is running.

So when the wiper is running the motor gets power from both the park switch in the motor unit, and from the stalk switch, except when the wiper is passing the parked position, where it only gets power from the stalk switch feed.

Typically the power for the wiper comes from the ignition ancilliaries circuit, and is split two ways. One way goes to the stalk switch. The other way goes directly to the motor unit, for the mechanical park switch.

The wiper it's self is quite a heavy load, so there may well be a relay in the feed from the stalk switch. The park switch in the motor unit doesn't really need a relay (other than the one on the ignition ancilliaries) because its a big heavy duty beast, operated mechanically from a cam.

I think Crafty is your man, I know he has recently installed a Mk4 Stalk so I'm sure he would have sorted out the park problem.

Sorry left this one alone as I have no experience of the Ford stalk setup but having re-read the OP I can help.
The park function is completely independent of the switch function be that stalk or factory switch.
There should already be a green (ignition switched +12v) going to the motor pin 53a. if this has been removed it should be reinstated.

When all other switch commands are off and the wiper is not in the parked position this supply will continue to power the wiper until an internal switch in the wiper says it has arrived in the park position.

Guys,

Seem to be going backwards here......had everything working just needed to wire in the indicators/hazard which seemed the easiest bit of all so had left that to last.....now however I've hit a problem....previously I had wired the lights using pin 31 as additional live feed for the flasher relay I had added.....lights all worked ok.....(Crafty - looking at your wiring diagrams under "a question of stalks" seems you did same?)....problem is that pin 31 is common switch unit earth with the Ford plug in flasher unit!!

Now I have working indicators/hazard but can't seem to get configuration working for the lights......appreciate any help from you MK4 switchgear guru's....Crafty, GTRsimon??

Fed up with wiring now so gonna get on with me headlining!!!!

Thanks again all......

Simon

Guys,

Nearly forgot......I'm running the new LED rear lights and using either the factory or Ford flasher unit blinking rate is to fast when indicating only....on hazard blink rate is ok |(higher load with all flashers on).....so looks like I need some additional line resistance for the reduced LED load over conventional bulbs......I'll give the factory a call in the morning to see if they have an easy fix.....

Back to the headlining...

Simon,

Give me a call and I'll put you in touch with my man, Adrian. He is a whizz with the wires and sorted me a set of stalks in a tick.

Cheers

Pete

I've got Mk5 switches. Connections for Indicators and lights are:

R: Right Indicator
L: Left Indicator
30-9: Constant +12v for Hazard
54-3: +12v for Hi and Lo lights
49: Constant +12v for flasher
56a: Hi beam
31: Earth for Flasher
55: Lo Beam switched (not connected in Ultima loom)
58: Side lights
56b: Lo Beam
30-7: +12v for sidelights

I just stuck the Ultima supplied flasher unit into the socket on the stalk switch. The connections to the Ultima loom were then real easy, the only extra thing I had to do was run a fused wire from the ignition key to 54-3 and 30-7 so the lights cannot be left on by mistake. Note that 30-9 is connected to a pin on the back of the stalk body, so is easy to short against the steering column (I blew loads of fuses before working that one out!).

Andrew.

Thanks guys....

I've got a set of MK5 stalks and they are quite different in design and pin assignment from the MK4......

Pete....call you in the morning.......be good to have a chat with you and Adrian.....couple of questions for you!!

ATB, Simon

PS....i've also got a set of those pedals for you to road test!!

My dash is still in bits - work has been too busy to get back to it. CF panels are being finished in the states now - final instructions given last week.

Here's the link that shows how I wired it (and shows I havent been in the garage for FOUR months!!)

I downloaded an Escort manual for MK3 & 4 here:

There's a couple more on the site - dunno if they are the for the MK5

Thanks Crafty....

Already cribbed all the info I could off your earlier post......left it alone for most today but gonna have another look in the morning......think I might have sorted it on paper at least - though it's now 1.50am & I'm tired so probably not right???!!!!!.....

However, looking at your wiring diagram you link pin out 30 and 31 just as I did originally....in this config and changing switching on high beam blue/blk via addt'l relay all ok (in other words used 31 as feed out to new relay).....as per post above hadn't realised 31 was common earth for flasher unit that plugs in to rear of the stalk........hence lost some light functions in gaining correct indicator/hazard operation! Quick question - did you use the plug in flasher unit or keep the 2 original Ultima relays??

Thanks again....if I get stuck again tomorrow I'll give you a shout!!

Not really following you there. I do remember that I had a similar problem where it all seemed to work fine except for one function, and when I fixed that something else went wrong. The Escort system is partially positive switched and partially negative switched. When they designed it there must have been some old bd from Lucas working there.

Finally I worked out how to change it all to +ive switched - which is what the diagrams show. This is only 4 relays (The Escort originally had 6 relays)

I rewired the flasher unit separately

Ive not got it in the car yet but have bench tested it and it seems to work.

No probs, anytime.

I forgot about the pedals!! Ooohh! Good timing. Will be working hard on engine install this weekend. At last!!

What year ford escort Mk4 stalk should I look for? Also, I will be going to a salvage yard to get one (if they have one on the lot) for $25. Is that a good deal or can I buy one somewhere else without having to go to the salvage yard? eBay???? What tools will I need to remove it from the car?

Thanks,
Paul

You can go for Mk4, 5 or 6. There's always a few on ebay.

Mk5 and 6 Escort stalks are longer:

Van ones are good imo as they don't have the rear wipe.

the Mk4 are stubby:

Thank you. I like the Mk 4 version better but don't want the wiper stalk on the right. Is there a good argument FOR going with both? In San Diego, I don't ever drive the car in the rain so although I have the wiper motor installed, I won't ever drive it in the rain. So the switch in the dash is just fine. All opinions welcome.

I think the mk4 stalks are seperate and can be split - lights/indicators on left, wiper on the right, so you could perhaps just have the light stalk, although it may look a little odd?
