I did a dumb thing tonight cleaning the solenoid contacts, I unhooked the ecm wires that trigger the solenoids for the grid heater and didn't take note of the wire colors and location.

If you're looking down at the solenoids on the battery tray you'll see what I am a speaking of. There are four 16 gauge ecm control wires (the smallest wires on the solenoids) attached to the solenoid posts. If someone can take the time to look at their wires and note the wire colors in order from the firewall to grille it would be greatly appreciated.

Thanks a million,
Eric

 

how do you clean the contacts??? does it look like this?

 

and... i dont think it matters which wire go where.

 

Yeah, it don't matter which way.

 

one small wire is power to energize the solenoid, the other is ground so it makes no difference

 

As long as you don't mix the pairs up it doesn't matter.

 

Wow, a picture is worth a thousand words as they say! Yep that's the part, those little posts (not the big copper looking ones) are the items in question. My battery some how started leaking acid on it causing corrosion and also my darn charge pipe (found my boost leak).

Thank you so much fellas.

 

On a side note, does anyone know if and where the relay is for the control side of the circuit?

 

Oh yea and to clean I just used battery terminal cleaner, foams up and rinse off.

 

It's in the PCM.
