I’m trying to find splices AD and S but I am struggling.
Help needed from anyone who has dissected the electrical system.
AD is TC switch, fuse F13, ECU ign, and fuel pump relay.
I have located where the TC goes into the main harness and that green 0.5 wire is heading rearwards. So AD is definetly at least behind the gear lever .
S is Purple 1.5 from fuse F11, purple interior light (behind seats), siren, and alarm unit. Where is the siren and alarm unit located?

Andy D is your man.
What are you trying to achieve?
OEM like battery isolator installation.
I could of course run wires from the relay to the front fuse box and back, but if the splices are closer and accessible I’d like to go that way.
Why would you need wires to the front?
Obviously the primary circuit cuts the battery feed, you just need the secondary to cut something to kill the engine and stop it running on under alternator power. Just intercept one of the engine fuses and loop it via the second switch circuit.
Assume you’re using the Tyco / Brise switch?
Yes, I’m using a Tyco relay.
I got the Cup car wiring diagram from Lotus and there are two wires going to splices S and AD. In the non Cup car diagram the equivalent wires come from fuses F11 and F13.
This has to to with the immobiliser / alarm unit function.
Unfortunately Andy’s expertise covered the S1, not S2.
I still have not found those splices.
Maybe time to surrender and splice into the front fuse box instead.
