Exige S2 Starts without Starter button!!

[nightSpirit]

Ok, so the other week I had a blonde moment and crossed the terminals on the race battery. This blew 20a fuses going to the ECU (Audi 8P engine converted car) x 2 and also a few 5-7.5a fuses under the access panel.

I sent the ECU off to BB Reman (ECU repair shop) as the 2x 20a fuses would blow constantly and the car wouldn't start (crank but not fire). Today I plugged the fixed ECU into the car and the 2 fuses no longer blow...and the car starts, but we have a rather strange issue! Now when I turn the key to stage 2, the car will start the moment I disarm the alarm (stock Lotus item). If the alarm isn't armed, simply turning to stage 2 will start the car.

I've tried unplugging the starter button but it still does it...any thoughts? Sounds to me like the wire to the starter button from the ign barrel has a bad contact but I can't see anything obvious Please no laughing or judging my stupid mistake! I know I'm a tit and still can't believe I did it after 15 years of working on cars...

Nice!

I think the wiring is Lotus (starter button) and I'm thinking (god knows why) that the hack (both pics below) has been done because of the ECU maybe?

pin on ecu bent out...odd


third wire in, wired to the first...more odd!

Ok, so Ive tried all the relays and fuses I can find...it looks like the 4th connector to the starter button (one to trigger the crank?) Has a permanent feed. Can anyone point me to the wiring diagram for the starter button and where that wire goes to (green)
