450 SEAC spare wiring - calling all Penelopes......
Discussion
Hi not sure if anyone can shed some light on an issue I have with the 450 SEAC I'm recommissioning. I'm working my way around the car, sorting out issues as I spot them. One of the jobs was tidying up the engine bay. What I discovered next to the battery was a large bunch of wires all taped together, with no connections to them. I've now completely removed the dash board to get access to the full wiring loom and these 17 spare connections are all part of the main loom, and definitely not a retro fit.
The wires are in two bunches, all terminating in spade connections. Bunch one consists of 2 black cables, 4 blue/red cables and 1 blue/green cable. Bunch 2 consists of 1 red, 1 purple/red, 1 yellow, 1 white, 1 green/brown, 1 slate grey, 1 yellow/black, 1 white/green and 1 white purple. See photo below.
I have gone through all the Wedge wiring diagrams I can find and none seem to have anything that covers these cable combinations. The 400SE/450SE wiring diagram certainly seems correct to all the rest of the wiring under the dash and through to the fuse box and relays. I have looked at optional extras that might be the reason for the spare. TVR did offer AC as an option and certainly around half of the colour combinations would match the AC option, but that leaves half of the wires unexplained.
As they are not being used my plan is to unwrap the loom back into the main car interior, and then cut the surplus wires back and heat shrink the cut end. To unwrap the entire loom all the way back to the fuse box will take an absolute age so I'm not intending to go that far.
Anyone got any clue as to what this wiring may have been designed for? Other curiosity is that the original owner does not remember there being a bunch of spare wires so wondering if at some point (maybe during its rebuild 20 years ago?) the loom was swapped??
I have now also removed a total of FIVE old burglar alarms that were dotted all over the car. That wiring was obvious so I've chased it all back, disconnected it all and put all interfered connections and wiring back as standard.
Any help would be appreciated. Thanks.

Does this help???
Early Cobra alarms used an 11 terminal plug and socket for alarms with battery backup that were fitted in the engine bay of various vehicles, same as shown below
Looking at the below engine bay found here https://www.pistonheads.com/gassing/topic.asp?h=0&...
an 11 terminal plug and socket connection can be seen by the battery, enlarged below
Guessing but perhaps this is what the cables are for
.........................................................................................
Should the above guess not be close, due to those cables being of similar length there is every chance that they could terminate to relays and/or aux fuse-box when put into use
Could try switching hazard flashers on and see if 2 of those cable are connected to indicators, alarms hook up to indicators

Hi "Penelope", as usual I think your information is spot on and this would make sense. There are also three holes through the inner wheel arch which line up exactly where the cables were coiled and presumably an alarm sat. Of the 17 cables, two are joined with a cross over so when I cut back I'll ensure I solder the pair up properly. No crimps, scotch locks or bodges - honest.
Thanks Again. Cheers.
