Does anyone have a link to a wiring diagram for a 69 mustang.I wasn't the one that removed the harness and I think some of the pigtails are missing. I am also installing a 3G alt,Electric Fuel pump,Security system,Electric Fan and MSD 6 IG . I think I can do this but I welcome any help.
I'v been there but I have seen alot better ones for 66-68 mustangs. I was hoping for one of those.Anyone now approx how big a relay is needed for
2 -11" Spal Fans.
I'd use at least a 40 amp relays on those fans, they can draw a lot of current on initial start up and can fry the cheaper lower rated relays so that they stick on and burn them selves up.
Spal makes a PWM fan controller also that runs the fan 1/2 speed at a user programmed low temp and then kicks on full speed at a user programmed high temp. Around $70 is what i paid. I like the fact that it hooks up to the existing temperature sender and doesn't need a probe for the radiator.
