Does anyone know if the GMPPs harnesses have the fuel pump leads/feeds and relays? What about for dual electric fans?

 

Fuel pump........Yes....Single fan.........Yes.......Two fans.......I use relays....

Not to hijack, but does GMPP sell just the fuse box? Or does anyone know who makes the fuse box?

 

Bussman is commonly used. BP Automotive will sell the fuseblock.

 

Like others have said. The GMPP harness has the relay & about 12" long wire for the fuel pump. Same for the fan, single relay, & about same 12" wire if I remember correctly, you could run dual fans off of one relay but obviously both will kick on/off at same time. I converted mine to use the Corvette fan & PWM control.

GM used the fuse panel/box in production vehicles. I found one in a junk yard one day, I believe it was in a full size van. But couldnt tell you who makes it. Probably Delphi or Packard Electric Division.

I have snagged stock fuse boxes from junk yards over the years, but they usually end up not having enough fuses or relays. Do you know what year of van to look for?

 

Sorry, no, I dont know my GM vans & this was a few years ago. I just remember that I walked by & looked in the engine bay & saw it.

 

I looked on ebay. This one looks like it is the same.

What are you looking for?

 

Scot, I read through the pwm thread at either PT or lat-g. Did you have to reflash another file to get the pwm to work? I remember the GMPP pcm file didn't originally support the PWM stuff.

 

I have HPTuners, I had to change the fan setting from discrete to PWM (or something like that), basically from an analog on/off signal to a variable signal. The GMPP PCM has the option already there. I had to add the wiring for it, temp sensor is already there, added the AC pressure switch, and signal wire for the PCM module. PCM will control cooling fan speed based on AC line pressure as wel .
