I am going to use 8AWG. That crosses to 3.260 mm diameter and 8.350 mm2.

I hit a snag with the relay/fuse box I mentioned earlier. I can't get the relays ganged together. The 8AWG is already in place. I need to find a way to split it into 5 14 AWG lines to go to the relays. Any ideas???

 

I bought a Painless kit that is weatherproof and provides circuit switched and constant on power. I have installed it between my battery and OEM fuse panel.

 

I am running a 4 AWG wire.

 

What kit are you refering to? Do you have a pic?

 

This is the picture from the Painless Performance website:



They have other options. For example you can get a 7 circuit in 40 amps as well as non-weatherproof and 3 circuit versions. I found this to be the easiest way for me.

 

I used this method for building my power supply. I used 4 awg because this wire is good for 80 amps. I split it down to fit into ( 4 ) 10 awg butt splices.
I think that 8 awg will be too small by the time you split it down. But, you can get by as long as you do not put more than 40 amps across the 8 awg wire. Just peal the insulation back several inches. Then devide the strands into equal groops. Re-insulate with tape or shrink tube.
P.S. If anyone is intrested, I have a build sheet worked up for a custome wire harness. Atleast what I have done. There is room for improvement. But I will be glad to E-mail anyone a coppy. Just P.M. me your E-mail address.

 

I found this at Scosche:



Part Number: PDM48X4I
Product Name: FUSE HLDR MAXI 4OUT ICED

Description:
Maxi Fused Power Distributor; 4-8 gauge: one 4 ga. in, four 8 ga. out; for Maxi fuses. Platinum Plated

For $30 it seems to be the best thing going. Standard blade fuses, 4 outputs, and cost effective. Or am I missing something?

 

And then I went in another (final) direction. From the battery I have 4 AWG going to the same distro/fuse block as an amp. A 4 AWG line goes from there to a PAC-80 Relay. Using a 4 AWG terminal I crimped and soldered in 6 14 AWG wires to feed 5 relays with fuses and 4 other fuses. The 14 AWG feeding the four fuses will be for CB, GPS, and some LED stuff I am doing inside.

This is the last design but I have said that a lot of times already. We'll see.

 

I got a 6 circuit fuse panel from OK Offroad. Mounted it high left behind the glove box and ran 4 GA wire from the battery. Connected interior lights and CB without relay. Used relay for bright back up lights.

 

Ok, here's my parts list so far.

4 x 100 Amp Circuit Breakers
4 x 20 Amp Maxi Fuses
4 x 20 Amp Relays
4 Gang Fuse Block rated at 20 Amp per circuit
12ft x 2 Pair 19 GA wire
10ft x 4 GA wire

This will all be made into one fuse pannel containg 3 independent circuits.

Circuit 1 - Car Audio
---------
4 Ga from the battery to a 100 amp breaker.
4 Ga from 100 amp breaker to car audio amp.



Circuit 2 - Winch
---------
4 Ga from the battery to a 100 amp breaker.
4 Ga from 100 amp to a future winch (may need larger ga)


Circuit 3 - Accessories
---------
4 Ga from the battery to a 100 amp breaker.
4 Ga from 100 amp breaker to fuse box.
20 amp fuse to Windshield Lights via Relay
20 amp fuse to Bumper Lights via Relay
20 amp fuse to HAM/CB via Relay
20 amp fuse left in reserve for future mods.
19 Ga wire ran to a DayStar lower dash panel w/ 4 switches, one for each relay.



I think I've got a pretty solid plan here. Any problems you all see with this layout?
