Trying to identify whats described on the wiring diagram as the "Main terminals on bulkhead" would they be what I have ringed in red?



Also trying to source two of the 3 cylindrical Lucas relays for the same vehicle, according to the daigram they are all the same rating, they dont look like TR6 relays so could they be Ford?

those ref numbers match the square type relays (Bosch etc), and it looks like the base layout might be the same ? Just a thought ....

I have a vague memory that TR7 had round relays looking like that photo, could be wrong.

Hi Erich

No, the bolts on the ventilation channel is mounting points for the ignition coil.

The bulkhead terminals is 2 1/4" bolts with 4 lucas spades as a washer. You need to mount these just right off the hole where all the wires goes thru from the cabin. (seen from the front)

If you need some std relays, lucas pin connectors etc. please let me know, and I can send you some bit's and pieces. I,ve redone all my wires to Bosch style, so the original loom and bit's are overleft.

Any help ? I believe that originally a "spare" fuse box lid was used to cover them?





The far more common and readily available square relays will do the job but if you want the original look.... Lucas round relay


doesn't have 87a but I don't think any of the relays use that (made when not energised) terminal?

Hi Phillpot, that's a great picture that helps a lot, if you have any more of the wiring under the bonnet, particularly the thick stuff around the battery and starter motor that would also help.

Again thak you very much, just one point, they are from a 3000m or Taimar as there are some minor differences like the vent on the RHS?

Ok, just comparing it to mine which has a ledge just below, did that original arrangement on yours have a cover over those wires? On mine I would have thought the wires should go behind that black cover?

Looks like TVR did away with that ledge on the Taimar, no covering on any wiring just a few clips and lots of tie wraps!

So it's a coloured wiring loom, for an earlier version of the 3000M than what you have, AND it is for a LHD car...or it's something else.

Its from Autosparks for RHD 1976 onwards 3000m, they come with coloured wires as standard instead of the standard all black with heat shrink colour indicators, would have been extra for an all black loom would you believe.
