I'm doing the 86/87 ECM swap this weekend on my Hot Air T. I have electric fans already installed but my old aftermarket fan controller doesn't seem to be working. A friend is telling me to just by another aftermarket job. I figured while I'm doing the swap I might as well use the ECM with what ever wires and relay I get out of the donor car for the fans. With that the fans will turn on with whatever temp the PROM tells it to correct? Does anyone know what temp the Thrasher chip is set for? And does anyone have any better ideas for fan setup? Thanks all.
