Can the fans be rigged to come on while the engine is not running?
The following instructions are for all mid-1994 to 1995 production models. Slide two wires into the underhood fuse/relay box in the D2 and J2 slots for the #1 fan relay (D) and #3 fan relay (J). Splice them together and run them through a 1 amp fuse. Hook another wire to the ground. Then, with the ignition on, connect the ground wire to the spliced fan wires and both fans come on at high speed. When you’re not using the setup, remove the ground wire and tuck it away so you can’t see it. The J2 slot is also connected to the F5 slot in the #3 fan relay, so you can use either one, it seems. This essentially provides the ground signal to the relays just like the PCM would when FAN CNTL A10 and FAN CNTL A11 codes are set in the PCM. The relays click when you make the connection, so everything should be working just like if the computer set both codes. This set-up requires the ignition to be in the “On” position and requires no splicing/cutting of any stock wiring. This works great to cool o
