aftermarket power distribution (relays)

I have a bunch of things that need to be wired up shortly, and they all need relays. 2 a/w ic pumps, 1 fuel pump, and 2 water injection pumps. I can get them all wired up, but, there has to be an easier, neater way. I am looking for something that I can run one big 12v+ to and do the wiring from there. Anybody know of anything? I searched around at some audio stuff, but didn't see what I am looking for.

Go to a bone yard and get one out of a ford crown vic police car. might even look at the f-150 deal mounted on the firewall pass side.

Re: aftermarket power distribution (relays)

ahhh if you need the police junction boxes I'll see if I have any around. I usually pull them out with the police wiring and toss them. But I might be able to find some if you want. PM me if that's what you end up needing.

I guess I would need to see what one looks like, but I can imagine a police car requiring a lot of relays, and should work fine. When you have time, that would be great! Thanks!

Re: aftermarket power distribution (relays)

I'd use a fine strand 8 gauge for the power wire. I'd power all of the relays with the same wire. Then I would install a small short connector from the power terminal to the + side of the relay coil and switch the - side. You might even find a relay that is internally wired.

Re: aftermarket power distribution (relays)

you can always run a larger wire to a dist pannel then tap off that.
each can have its own feed, fuse etc. there was a new product in one of the diesel mags not too long ago dealing this very problem , basically it was a small box or series of boxes that distributed power but was suppose to use far less wiring. have a look at some boat shops etc, they have hundreds of different sub pannels, distribution blocks etc.
