What gage wire is used in the inj. harness? Thanks
Also there are 3 wires in the cooling fan harness
Solid black
Black with a pink stripe
Black with a red stripe
I assume solid black is ground
I have no AC so which wire will run my fans off the ecm signal?
Also does the fans go to ground to run?

fans are switched by ground- thats all i can tell ya off that list

From the service manual I get .8 metric which is 18 gauge on their chart.

I didn't measure anything for verification.

Solid black is ground.

Black with red stripe is low speed and terminal A and goes to low speed fan relay output.

Black with pink stripe is high speed and terminal B and ges to the high speed fan relay output.

Ground is direct to ground the +12 volts is switched via the relays.

Low speed operation is ECM controlled.

The low speed operation had the black/red wire going through the factory resistor at the fans for low speed.

Thank you

Exactly what I needed.
