The Stovebolt Site Forums The Shop Area The Electrical Bay EZ Wiring Installation Questions

I have a '50 Chevy 3100 with a '60 235 car engine that has all been rebuilt. I have added an electronic distributor. And I am now installing the EZ Wiring 15-circuit harness.

It's been difficult to follow the circuits on the harness with no full wiring harness. The directions leave something to be desired. Afterall, the whole truck can be wired in 5 steps? So I have a couple questions.

Question #1: brake light switch and high beam switch; the wiring doesn't seem to be there for those two switches on the firewall. There is extra length on those circuits. Should I cut the wire from the tail lights at the stop switch and connect both sides to the switch? Should I follow the circuiting of the original truck or assume that it's all in the wiring harness and just continue forward blindly hoping it'll work? ;-)

Question #2: alternator wiring. The instructions for the kit show a voltage regulator on the system. Is this already wired in? Do I need it?

Thanks for any help. Feel free to shout out what other information that is missing that may be helpful.

RedGreen,

I have never done a EZ harness. The brake light switch and dimmer switch are both way down under the toe board so there probably is extra length in those wires.

If you don't have after market turn signals, then you are correct, the brake switch is wired in series between brake lights and a fused source of power..probably in your new fuse box.

The wiring should be there and well identified for that brake light switch, as it's a standard issue deal on all the AD trucks.

If the harness is for a generator equipped rig, the wiring won't be proper for a alternator equipped system. This isn't true if you bought a generic harness that would cover both applications.

Your directions or ordering info would probably state if the wiring was 'alternator ready'.

Does this answer some of your questions?

Thanks for the info, Stuart. I understand how the brake switch is supposed to be wired on the truck. I guess I'm asking for help specifically from those who have used the EZ kit. I'd like to hear how others did it because there is only "tail light" wire going from the back end to the fuse panel. According to the truck wiring diagram, this wire should be interrupted by the brake switch on the firewall.

My kit is definitely for the alternator. The directions show a voltage regulator and one of the earlier posts had a link showing the same thing. Again, for those who have used this kit, how did you handle the alternator wiring? Did you have to add a voltage regulator?

Thanks, David.

Hello,
I used the EZ wire kit. I really like it. I modified my generator bracket to accept a GM alternater w/internal regulator. The alternator sit towards the bottom of the motor so it isn't that noticeable. It's a much better system. The original ampmeter still works fine.

I have the 21 circuit unit but will look to see how the brake switch is wired.
