Wiring loom

[Alex93]

Forgive me if I'm meant to know the answer to this but please help.

The loom straight out of the box has approx 40 connectors which can be labelled with the list of 1 - 87 as supplied. Now, where would I find a list identifying past 87.

Also, what of the rest of the list that aren't attached to the main loom. Are they on sub - looms or different?

Furthermore, how does the loom need to be changed to work with a Dash2 Pro system and how do they all connect up together?

Thanks for all your help

What makes you think there are more than 87 units to connect too?

There are only 3 parts to the loom the main body and the looms for front and rear clips. The loom is also designed to work with an SBC running MSD ignition. If you are using a later engine and ECU again you will need to work out yourself how to modify the loom. If you buy your (LS) engine from the Factory it will come with the engine loom and instructions on how to wire it.

As the Factory loom is designed for individual instruments you will have to make your own mods to make it connect to a Dash2.

Only because some connections are labelled numbers above 87.

We're going for an LS7 from Schwartz performance we think and will go with the general consensus regarding ecu.

Anyone out there who'd be able to help regarding wiring of the Dash2 pro when needed?

sounds nice, which power level u going for?

[Alex93]

730 of the finest American stallions I think

If they are labelled that way then you had better ask the Factory as nothing I have goes above 87/88

Send me a link to a circuit diagram for the Dash2 and I will do you some instructions.

I'll drop the factory an email.
Okay I'll do that when I'm back with the unit on Tuesday (I'm a student living away from where the car is) but I'll send you an message if that's okay when I've got a circuit diagram.
Thanks a lot mate

good choice, look forward to seeing some pics of your build progress

Will you not have to use the ECU that Schwartz uses to get the engine to produce that power? I assume he does one ready mapped for his engines.

I've been a bit sporadic taking photos of the build so far but I'll post some that I do have when I get some time.

We'll use whatever ecu schwartz say to use which will be the one they use for the power. Would like to have two settings on it though, IVA and maybe an additional setting for when I want a bit more maybe? Is it possible?

Ive got a FAST xfi ecu on my 383 sbc vette, you can have 5 different maps on that and then a switch to put it onto any map you like

I don't mind admitting that I currently know very little about ecu's, so need to do a bit of research but I'll talk to schwartz and see what they say regarding what they recommend vs what we want to achieve

good plan, also have a holley dominator ecu on my LS3 engine race car, which can do the same, iam no expert either, but have a little knowledge of these 2 cos i use them

In terms of wiring the engine loom is pretty much stand alone. It will require a heavy duty supply and an ignition trigger. Then a few sensor wires and that's it.

This multiple map thing baffles me. The whole point of a map is to have the correct mixture for every condition so if it has been done correctly all you would want is in the one map.
The exception would perhaps be the IVA map where the engine will not run happily at that mixture and has to be forced there to pass the test.

Good point Steve, examples of what u can do, you could have a garage mode, ie a rev redistricted mode type thing to stop the local garage taking your pride and joy for mad joyrides lol

the main advantage would be on forced induction engines, so you could run different boost levels on the turbo's etc

different maps for different fuels, say its mapped on v power, but u on a long run, have to stick some, poorer fuel in, then switch to a map for said fuel

concerning the engine wiring loom, its a really easy as Steve said, Ive done it 3 times now on different cars

May be worth speaking to UK owners that bought this 730hp package before you commit. Or get assurances from Schwartz it will pass IVA or can, and whether it will require a remap pre and post, and confirm if it'll pass then not need a remap, how much power it will actually produce.

I think 3dee had this package and ls7tango, both needed a lot of remapping to get through iva. Is obviously doable, just go in with eyes wide open

I can help with Dash2 modifications / wiring..... I've actually got XL & Word docs that show how I've made modifications to the loom, for everything I've done. PM me with your email address and I'll happily send them over.

Dash2 is easy enough to plumb in, the trickiest bit is setting up the resistors to allow the dash to work with the standard fuel senders.

[Alex93]

Thanks to all that have offered help with the Dash2 pro system. I can assure you its very much appreciated!
Regarding the engine, after talking to the factory I think we may go with the American Speed option due to Ultima's influence in making it so compatible with everything else.

I'll post some pics soon for those that are interested In our build progress.

Alex

AS is a good choice and is factory supported and IVA compatible (in principal).
