I have searched but can't seem to find what I am looking for. Is there a wiring diagram for the wiring update (Service Bulletin) that should have been done at the fan relays? Page Z40 in the Wiring Diagram shows the coolant fan wiring and the relays but it doesn't seem to match what I have. I am doing a little troubleshooting (actually trying to put some jiggered up wiring back to stock) and having trouble following the manual.

I have a short harness made up of three individual harnesses which plug into relays #2, 3, and 4. The other end of this short harness plugs into connectors which lead off to the fan motors. I would like to verify I have the correct connections at that point. But I seem to have more connectors than the wiring manual shows. Plus I go from 4 wires at the relay to 3 at the other end. I know some wires (blues) have been tied together but sure would like to see a diagram.

Is there an updated diagram available anywhere?

Thanks,

Jeff

 

Ditto to this poor guy who asked the question 7 years ago.

The prior owner installed Flex-A-Lite fans and one of them shorted out which has melted my connectors from the relays to the harness of the car. Long story short, I'm in the same boat as this dude and can't find good information. I have the wiring diagram for the relays but it doesn't show you what to do when you have 4 wires going into a connector and only 3 coming out.

I planned to cut the connector at either end and just splice/butt connect them together for a good, solid connection again but I am confused with 4 wires going in and only 3 coming out. I don't know how to approach this.

Anyone have any ideas?

The color code for the 4 fan relays does not match the schematic color code in my manuals.
Japan still getting back at us for WWII, Ha Ha!

 

Yeah dude each relay connector has 4 wires going into the 4 pin connector but then there's only 3 spades inside the opposite connector. There's apparently 1 unused wire in each relay wiring.

Mine were melted so I had to hardwore. I hope it's right...
