Anyone,

a good guide to fitting esp wiring schematic is required so we can fault find
Bought a second hand plug and play GEMS for 99my.

this was originally fitted to a UK 99 and is now in my WRX STi V type R.

First place to fit it - could not finish the job, but did install it (long story)- they managed to get the engine retard advance switch to work (95 fuel map) and fitted the Anti lag switch but said they hadnt mapped it yet - and they never did.

also when i picked up the car ---- the water spray was pumping constantly with the ignition key on 2nd position?????

Second Place - have mapped the car wondefully !! but still can not get the anti lag to function. has anyone got the correct wiring diagrams for all connections??

as I understood

ALS is just a switch INPUT (i.e. it activates a MAP in the GEMS with no other connections)

ALS OUTPUT was via the ECU into the factory loom with no other connections


any help most appreciated
