I'm about to solder my fuse block wires to my engine harness wires and I need some help. What is the best way to deal with the coil and injectors Pink wire to the 1 pink wire at the individual banks at the fuse block? Is it easier to step them down and have one wire the full length and the others tie into it every few inches until you only have one wire? Not real sure what to do. What have you guys done. Thanks in advance.

Split the driverisde and passenger side into separate circuits each having a single wire run from the fuseblock. Near the rear of intake manifold split the single wire into a separate wire for each circuit. The split should be done so the wires are run in parallel and not in series.

Your thinking will work fine. You'll need one 15 amp fuse for even numbered coils and injectors and one for odd.

So should I use the front injector wire and run it back and for the other injector wires and the coil wire, splice into that one wire so they are parallel?

That would work fine as long as you only use the one wire to supply power to them. That's all you need.

What gage wire would you recommend?

18 gauge for the coilpacks and injectors harness

I did it exactly as your thinking, I used the longest wire and never broke it, I stripped it, wrapped the next wire around it and soldered it. That way if i ever have an issue it will only be a single issue and not a solder connection causing an issue with an entire bank. kinda using the idea of "your only as strong as your weakest link"

on this note i have a question in this same setup.

not to rob your post but figure good info start lets keep it going.

i did the coil pack and injectors for odd and even on there own fuse. so there is a odd fuse and even fuse with coil power and injector power on same fuse .

my question is 2 part.

is this o.k. ?

and if so what size fuse should i run in the 2 fuse spots. ?

thanks as always

sweetk30- That should be fine. Most/some people run left and right bank fuses instead of odd and even but it should work. It's mainly there to prevent major damage in the injectors or wiring.

Unless I am missing something you are both saying the same thing......the drivers side bank is odd (1-3-5-7) and passenger side bank is even (2-4-6-8).

Yeah your right. I got confused for a second.

I necked mine down like this: 5 wires on the driver's side down to two wires down to one wire into the fuse box. I used solder and adhesive-lined head shrink tubing. Repeat for passenger side.

If I had to do it again, I would get a butt-connector and run all 5 wires into a a single wire that goes to the fuse box, for each side. After crimping, I would add a little solder into the butt-connector and cover with stiff-walled adhesive-lined heat shrink tubing.

Although I usually prefer solder+heat shrink tubing connections, I think this is one place that a butt-connector really makes sense.

o.k. good info here but as i asked before whats the general idea for fuse size on a setup like this with coil pack and injectors per side . ? i see 1 guy has said 15 amp .

all driver / odd side on 1 line / fuse and then pass / even side on seperate line / fuse.

15 amp ? 20 amp ? 25 amp ?

just wana get this right so i dont go on a test drive out in the country or heart of the city and have the thing pop a fuse and die on me.

I followed GM's lead and used a 15 amp fuse for each side. Other guys do it differently, and run more wires on a larger fuse.

I don't think a larger fuse would be required if you ran both banks to one fuse... the fuse is there to protect the wiring from over-current and melting, so upping the amperage is not a good idea.

Also since only one cylinder fires at once, I see no issue running both banks to a single fuse; the "duty cycle" will be greater but the max. drawn current should remain constant.
