Ez wiring my _____

[superlifted]

Well I'm almost done with the wiring of my ez harness. I wish I would have kept the stock harness now but oh well. I have a demon in my headlight switch. When I pull two clicks on the headlight swith I get lights and park lamps. When I push it in one click I lose head and tail lights. It a new switch, new harness. I heard that there might need a wire to splice but I'm not to sure. Any help would be appreciated.

i believe your 71 headlight switch is the same as this pic, if your using an oem headlight switch
you'll need two hot wires feeding the switch; the obvious red 12v input only powers the headlights and dash lights
the orange dome/courtesy terminal is marked incorrectly in the pic, it needs 12v power and had a separate fuse in the oem fuse panel
the orange wire feeds that side of the switch... the brown parking, side marker, plate lights
this circuit feeds the dome light in the stock harness, but it needs power to light up the parking, side marker and plate light
it was originally the brake light fuse

what concerns me is that your side marker lights work with the switch all the way out
you have something feeding the circuit, i suspect you have the lt blue (dimmer feed) wired to the side marker and tail lights
you do not want any other load on the headlight breaker other than the headlights (ezwire uses an auto reset breaker for headlights)
separate the side marker, tail and parking lights from the headlights; use the brake light feed to power the orange feed
the lt blue hi/lo should on wire into the dimmer switch, nothing else

vetvette will chime in to say if i've done this right
i've never actually wired this particular headlight switch, just read the wiring diagram

wiring diagrams from another vetvette post:

first pic shows your oem fuse panel... follow the orange wire...
you'll see it feeds; down to the ''dome lp conn'' and up to ''stop lt sw conn''
follow the orange wire from fuse panel to the right off the page (to 2nd pic)



2nd pic follow the same orange wire from the fuse panel to the ''light sw conn''
also note the red wire goes to the same ''light sw conn''
then follow the lt blue wire it only wires the headlight switch to the dimmer switch



not that your using any of the oem panel or wiring, i'm just showing you the orange wire,
how it feeds the oem brake switch, dome light and side marker lights

if this makes more sense.
zoom your browser out (hold ctrl down and roll mouse wheel)
and you will see the 2 wiring diagrams side by side

You are correct. I had someone hook up my wiring harness for some extra money and he hacked my old harness and new harness and left it half done. I'm going through and piecing it all back together. My switch is wired wrong. I'll go through it tonight and try to fix it. thanks for the help.

ok I removed my jumper from the blue wire and got power to the orange wire and the lights work like they should thanks for that. Now my bi problem is I have red alt wire and a white excite wire that are not pluggen into any thing. I have a internal reg 140 amp alt and a wire going from my alt to the starter.

i used ezwire in my 58, i know were every wire starts, goes and terminates
very handy for adding or trouble shooting
glad your headlights work correctly now... i cheated and used a one wire alternator

the manual does have a couple alternate alternator wiring diagrams
if you don't have the manual download one from painless performance
or wait for someone else to chime in (or start a new thread)

Noticed you figured it out but this might help others in the future, I have the same harness and happened to take a picture of my switch in the parking lot of the auto part store before changing out a fauty switch. If I remember correct the dome light was a bit tricky, I think the white wire that EZ provides to connect to the switch actually tied to the orange in the factory dome light wiring. I will check and confirm so you might want to hold off on the dome connection for now. One of the red wires on the double connection is a jumper but it gets cut off in the picture. All my light work properly.

Sounds like you have a "one wire" configuration for your alternator wiring. If that is the case you may want to use EZ wires to switch over to a 3 wire setup.

I realize it's not the same year model but I think they're pretty much the same and the EZ wires may not be color-coded the same. the white wire grounds the dome light circuit. maybe this will help:
