Swapped to TPI, but no wire for fan...how to set it up?
I've swapped to TPI, but the harness had no wires for the cooling fan (had a relay though). I still have my single fant TBI setup...how can I wire it up? Do I have to hook it up to the fan relay, or can I hook it up to the fuse box, ignition...what do I have to do? Thanks.

On an '86 VIN G or H, the Fan Relay wiring goes like this:
brn/wht-from FP-FAN FUSE to Throttel Kicker Relay to Coolant Fan Relay pin C.
Dk Grn-from coolant fan sw & A/C Control Head to Coolant Fan Realy pin B.
Red-from Fusable Link F to Coolant Fan Relay pin D.
Blk/Red-from Coolant Fan pin B to Coolant Fan Relay pin A.
The Coolant Fan Switch is in the block between plugs #1 & #3.
The A/C Control Head is in the A/C pressure line between the compressor and the firewall.
