Re: 1990 GMC Suburban ... Cummins Powered
What sucks is the dash was cut in the radio hole ... now I either have to find a radio that fits the hole or fab up a filler plate ... sucks because interior is basiclly all there .
Just did a change in the electric fan wiring ... went back to the paper work on my fans and the Hayden controller .
It is a dual control unit but not rated for the amperage my fans will draw ... was not that big of a deal I added two 30 amp relays ... just took the out put feed that went to the fans and plugged them in as the control power for for the relay ... I ran a new feed power for both relays and just connect them to a 50 amp maxi fuse .
