Dash Harness Installation

[Walter R.]

I am putting in a new dash harness and have a white wire with a female plug and do not know where it goes. the wire is on the group of wires that services ignition area. Also I have a grey wire with a a black plastic light socket and I do not know where it should be located. Other light sockets are the metal type. HELP.

Isn't the grey wire with the black plastic bulb holder for the light by the ignition switch?

The only white wire with a single connector I can see on the wiring print is to go to the the washer/wiper switch should have a female terminal on the end.

Re: Dash Harness Installation

I'll check to see if that is where the white wire should go. I'm still not certain as to where the grey light wire with the black plastic light socket goes.

Re: Dash Harness Installation

lt grey wire indicates dash illumination, look for a hole in the metal panel of the instrument cluster.

Re: Dash Harness Installation

There is only one left to put a light in and I have two lights, both with grey wires, but one has a black plastic receptical and the other a metal recepticle typical of instrument panel lights.

Walter,

Could that wire be the headlamp warning light #257 bulb as that socket needs no ground because it grounds at the headlight motor through the core support. Or the ignition switch light.

Walter -

I can't find a white wire with a female connector anywhere in the '66 harness; white is only used for the ground side of the courtesy lights and to feed power from the brake light switch to the turn signal switch connector. Does the black plastic bulb socket with the single gray wire have a metal shell inside the plastic? It has to, in order to provide a ground for an illumination bulb. The brake and headlight warning black plastic sockets have two wires each (light blue and gray/dark blue for the headlight warning, and tan and pink for the parking brake warning) and don't need a ground at the cluster.

Re: Dash Harness Installation

I'm not in possession of a '66 at the moment, does the ignition switch use a lamp?

Yes, it does.

Re: Dash Harness Installation

My original 64 harness has the same wiring colors as John mentions. It's hard to see the trace wire color of dark blue on the gray wire, in fact if John did not mention I would still think it was all gray. The two plastic connectors both have two wires however one of these typically falls out. See picture - the brown has fallen out of second connector, so look around for the other wire, black w blue trace. It may have just broken off. If you can post some pictures to make things simpler for everyone.
