Getting the wiring right! HELP NEEDED
Posted: Sat Jul 25, 2009 8:01 pm
Hello everyone I am converting a 1985 505 GTI to Megasquirt 2. I am changing the throttle body around to include IAC. I have correctly connected all of the wires thus far other than the injectors the fuel pump relay and the 12v+ supply.
The reason being I am confused of what relay does what and where is it. Because as far as i can tell my tachometric relay acts as my main relay and FP relay? Can anybody clarify this?
If so I obviously need 12v+ when cranking and running so which wire can i use or do i have to run a new wire of the ignition key?
I have included the OEM ecu wiring diagram for reference and also pictures.
Any help would be greatly appreciated!!!!
