Volvo 850 coil connection


Recommended Posts

You most definitely will need a supressor on the coil positive terminal.  From the wiring diagram it looks like you have it all sorted anyway.  Connect the yellow wire to the G2's Ign1 channel.  Connect the supressor to the red wire and ground as close as possible to the coil.

You wanted to inform that I have the car up and running. Volvo 850 2.5 ltr 5 cylinder with throttle bodies. Car is running like a charm, engine responds to ECU changes very well. Overall I'm impressed. The one thing missing, closed loop lambda control preferable from a wideband. (LC-1 in this case.) Regards, Johann
