ECU dual fan wiring?

[jlwdvm]

I have 2 AAW relays to use that were recommended by C&R (Built my rad with dual Spal fans for 69 F-body with LS)...one for each fan. My question is where do I run each of the 2 wires for each fan (4 wires total coming out of the ecu wire harness)? Maybe I have the wrong style relay?

ok gotcha....


grounding circuit shared with switches. repeat for second fan

Right...that looks similar to the directions that came with the relays. My question is: why dies my ECU harness have 2 pairs of wires coming out of it instead of 1 wire for each fan? Is one for a manual switch and one for a temp sensor switch? I tried to get a hold of Speartech, but no answer.

Can you turn the key on. I think speartech gives you a 12 volt wire as well, I have only used his harness once.

One wire would go to 85 and one wire would go to 86 on the relay.
