Ok so here's my problem.. I can't really make much out on the wiring diagrams posted in sticky.. I have the main harness wired up and I have the motor cranking.. Problem is I didn't grab the underhood fuse box and looking at the diagrams it appears I need that.. If anyone can help out I need to know which wire colors go to where.. And if they are supposed to re connect to main harness, the colors they need to go to would also be helpful.. Thanks for any help given..

well maybe its my misunderstandings then.. do i actually need the underhood fuse and relay box? im running my cooling fans on a switch.. and my fuel system is a complete aeromotive standalone...
im just wondering what is powering/driving the ignition(coil packs)..
again all help is appreciated.

Relays aren't "needed" but they do help prevent overloading electrical system.

I'm wiring up my Nova witha painless kit that has a few spare curcuits, I might just tap into them instead of running a relay. But then again relays are only a couple bucks each and I might just power them with the spares in my fuse block.

You don't need the underhood fuse and realybox that came from the donorcar. It has a lot of stuff you don't need.

How ever you need fuses and relays for proper function and safety. The wiring diagrams in the FAQ-section have all you need to get the car running. You have to add relays and fuses to your cars wiring system. Those diagrams are general and would help anyone do the wiring himself from a stock engine harness.

In my car I ended upp with 15 relays and some 20 fuses but I added some extra stuff to the car as well like AC and some electronics.

Here is your power and ground circuits, with the correct size fuse needed. Your fans will need to be on relays. A switch will burn up real quick. The fans pull too many amps for a switch.
