    Default Wiring help

    Does anyone have any detailed photos of their column wiring? I found to pictures on this site but I need better photos. The PO really hacked the column wires up. I would take a picture but my camera just gave up on me. Looks like the PO cut out one of the connectors for some reason. I think it's the wires from the turn signal switch to the brake lights.

    Ok Here's whats going on.

    From the turn signal switch to the wires that have been cut and sort of soldered to these following wires.

    From switch White/Red soldered to Green/Blk
    From Switch Green soldered to black/yellow & a white wire with flat spad connector
    From switch White/blk soldered to Green/Red wire

    Then there is also these three wires Green/red, Green/yellow & Green/blk wires coming from under neigth the dash up the column that are all soldered together. This just doesn't make sense.

    Then from the Combo switch to the connector and after the connector there are three wires that have been cut and are loose.

    From the combo switch to the connector the wire change color to these and than have been cut and are loose
    From Combo switch White/blue wire - connector- turns to blue/white and cut
    From Combo switch Red/blue wire - connector- turns to blue/yellow and cut
    From Combo switch yellow/blk wire - connector- turns to blue and cut

    Waylon;
    Problem is those members that DO know how to help you....have been forced off the site by the DarkFarters, the Tonyas and the other gutless nincompoops that endeavor to destroy this site as they did their prior home.

    Sorry, off my soapbox; PM forthcoming which should help. Flame suit on; CHECK!
    E

    Those that I'm referring to will speak up and voice their opposition.

    Default shop manuals

    I already have the shop manuals. The wire colors to the actual switches are different than shown in the manuals. You show me where the White/red wire from the turn sigan switch is suppose to go when the P.O. has cut out the connector so now I have 6 plus wires loose. I have all the down load wiring diagrams and stuff.

    The problem is that the colors, connectors and number of wires varies from year to year, and even from month to month in early cars. (Trust me, I know this part from personal experience.) This type of issue is exactly why I replaced my dash wiring harness.

    Lacking that, your best bet at this pint would be to get the multi-meter out and start making notes as you trace the wires. Because pictures will only help if we can determine which version of dash harness you have and find someone with the same exact version. Pictures of the wrong version might only make things worse.

    Take a look at the wiring schematic I linked in the PM I sent.

    You should be able to identify the wiring in the wire harness you have to the wires in your column since that's the identification page from an early harness (70-71).
    Then using the Multiple Wire Connector diagram, and the Single Wire Connector I also linked to, identify what wires went in to each of the connectors and rewire or replace as needed. Again, those diagrams are for the 70 and 71 vehicles.

    After 72, there were additions and changes to not only the wiring, but the connectors themselves as well as location of connections.

    OR

    Buy a complete Dash Harness (not going to be cheap, ask Arne) that matches the one in your engine bay and rear end (again not an easy task) and replace the cobbled up one in your car.

    OR

    Buy a complete set of wiring harness' for the whole car to ensure they mate with each other.

    FWIW

    As noted above, been there done that. I am very happy with the decision I made to replace the dash harness section.

    OFF TOPIC:
    Actually Will, I bid on the item you referenced (got to keep it secret) for the purposes that you and I discussed a few weeks back. I know that you've already progressed somewhat, but haven't heard that you've gotten further along. I have a few contacts that might be able to re-produce them and would like to have a set to show.

    ON TOPIC:
    Waylon: If you are still completely baffled, IGNORE the wiring color of the individual components, but DO trace the individual wires to their individual contact points to know where to connect.

    You could also replace both the Combination and Turn Signal Switches, except that finding the connectors for the dash harness may prove to be MORE difficult than finding a replacement dash harness. (Ask Arne about finding the right 6 spade connectors.)

    Please post if the PM I sent you helped.
    Enrique
