Relay board mounting

[The Hatter]

How are folks' relay boards mounted?

The one on the SEAC appears to be floating free, but I think someone tried to steal it at some stage and ripped it all out. The 350i has a plastic plate bolted to the bulkhead above the passengers feet and then several tie wraps holding the relay board to the plate; seems like bodgery but might be original!

I need to construct something for the SEAC so I'd like to know what TVR did.

Mine is fixed on a board, the board to a garden gate hinge, the hinge to the car and then the passenger footwell flap holds it all up, ECU and all. Then, as the slot in system for the flap is TVR, a luggage strap to keep that up.

Edit. Opps. Not a SEAC.

On my SEAC I can see the relay board used to clip to some back plate but the tabs have long since broken off

The solution a previous owner did was to run 2 strips of velcro behind the back plate, so the relay board can be held up via velcro, very high tec huh lol

(NB mines is the early 350i style interior)

Hi Martin

I have just been redoing my SEACs relay board so I hope I can help.
The relays and fuses are attached to a board which is held to the baulk head by two 6m bolts which go through into the engine compartment. At the bottom of the board are the two small garden gate style black hinges which are attached to a flap/cover which hides them all, I replaced mine as its made of hardboard and has over time got distorted.

The replacement cover in place.


The relays attachead to the board


The curved old hardboard cover.


A replacement marine plywood cover covered with the original covering.

Thanks all...

I'm interested in all variants not just SEACs, I don't think the SEAC is different in this respect.

+1 for the garden hinges.

I round that the self-tappers gave up holding the flap up, so I installed a furniture screw at the front that holds in the fiberglass, and takes an M5 bolt, which holds the flap up really well.

Trouble is, every time I put it up something seems to come loose so I take it down again, its been down for a few years now (except for BBWF!)

[The Hatter]

I have the garden hinge thingy...





but what holds the relay board itself up?

Andy it looks like you have the relay board horizontal and some kind of angle bracket to hold it there. Did you fabricate that?

Maybe I'm over thinking things and the relay board does just float around above the gate hinged flap without being attached to anything?

Hi Martin


On mine the relay board is cable tied to a fixed plastic relay bracket, which is screwed to the bulkhead halfway up the passenger footwell, if I can ill take a snap tomorrow.

Hi Martin

You are correct originally the relay panel just lay in place, we made a bracket to hold it in place. Plus a little catch to hold the flap up in place.

The relay panel on my car is assembled from interlocking relay sockets. At the four corners were clipped-in standoffs; these were screwed to a metal plate that was then screwed to the firewall; the standoff height created clearance between sockets and metal plate for the wiring.
Over the years and having suffered the attentions of whatever monkeys were let loose on the electrics the atandoffs had either snapped or were missing (I think one remains intact) so the entire assembly was lashed to the steel plate by a couple of cable ties that were so long you could have tethered the moon to the earth with them.
Although similar interlocking relay sockets are still available (from Ripaults and others) I have not yet come across the correct design of standoff.

In our part draws in work we have nylon stand off/spacers. Some with brass threaded inserts. Mine are OK but they exist in some form. Not original of course. Probably RS but must be cheaper out there somewhere.

Thanks for everyones help on this, it's now clear in my mind plus I found the panel that the relays mount to in a stack of mouldy carpet that I removed six years ago... time flies!



I have two stand-offs on the top of my relay board but the bottom two are missing so I'll have to come up with a plan; in any case the wiring is now quite 'set' with age and I don't think I could get the whole board close enough for the original stand-offs to work. They are pretty fragile and I think they won't take the weight/wiring strain any more.



I also eventually found a revealing photo from before I bought the car, I didn't think to look in that stash of photos earlier! Note the ECU wrapped in carpet and tucked up to the left of the passengers feet, the same as Andy's car.

Thats where Chris put his on the Gredge...There were actual holes there so it ended up being rubber mounted...I meant to check mine as it does seam a better place for the ECU as it is less strain on the wires, perhaps TVR changed their minds due to water ingress being a possibility in that area??...Not sure but it fits like a glove....

[The Hatter]

I suspect the reason most cars don't have it there is to save the cost and effort of wrapping the ECU in carpet to make it look nice!

Soon adds up mate...

Mine bares no resemblance to any of the photos.

I would like to side mount the ECU and split the relays to more local areas.
