Im installing a greddy turbo timer. I have a couple wiring questions that would be easily solved by the online shop manual that got removed. But anyways I need to know what the four wires are coming off the ignition are (colour coded) 1 should be accessory, 1 should be start, 1 should be power, and the other should be somethin else.... And then I need to know which wire is the speed(ometer) wire going into the ECU. tHanks

Accessories AND Run is Black/White

Run is Black/Red

Run AND Start is Blue

Start is Black/Blue

Speedo to ECU is Black/White, goes to ECU terminal 1M.

Thanks a lot for the quick response. So which of those 4 wires is going to be the 12v constant power. and how do i know which terminal on the ecu is 1M. Thanks

None of them; the wire with constant power is the Black, its the supply from the 100A main fuse.

and how do i know which terminal on the ecu is 1M.

I'll email you a diagram

PLEASE REPLY TO PUNK_WISE@HOTMAIL.COM THANKS A LOT

Done!

IanL,

Do you happen to have a diagram telling which wire is which in the diagnostic port under the hood? I have a 93 1.6 and I'm going to tap into the diagnostic port to use a lap top to manipulate the ecu. Any help will be greatly appreciated.

Thanks
