Howdy!

I'm just doing the finishing touches on my TPI swap into my 80 GMC pickup, the last component is my new fuse box, but I need to know what some of the amperages are. All these are coming off the underdash connector (I added a few wires for my convenience):

D Fuel Pump Power Feed
F ECM Power Feed
G EGR Power Feed

N Injector bank 1 Power Feed
P Injector bank 2 Power Feed
R Cold Start Injector Power Feed

Also, there is a heavy gauge orange wire that runs to the fuel pump relay, MAF power relay, and MAF burnoff relay, as well as to the ECM in two places. Does this wire need a fuse, or does this wire need to have a fusible link? Either way, what amperage fuse / fusible link does it need?

Thanks for any help you guys can help me with

 

Anyone willing to take 5 minutes to look under their dash and write them down? :lala:

 

The ECM/Fuel pump power supply should be protected with a 20A, standard time delay fuse.

The INJ1 and INJ2 fuses should each be 10A.

The EGR should be powered through the 10A GAGE fuse.

The Cold Start Injector and Control should be powered through a 3A fuse, identified as the CRANK fuse in many stock panels.

 

Thank you very much Vader!
