Turn signal issue, new harness, old aftermarket switch.

Hello all,
I've installed a new Rebel wire harness in my '59 Apache. It has been a breeze to wire, with tye exception of one aspect. I've hooked up an old switch that I have. I'll attach wire diagrams to this post. All four parking lights work properly. When I pull the knob out for hazards, they all four function properly. When I signal left or right, the rear turn indicators work as they should! HOWEVER, when I signal left or right, I am getting BOTH front turn indicators flashing!

I have an LED flasher installed in the fuse panel, replacing the original flasher. I have LED bulbs in my brake/tail lights, and incandescent bulbs up front for parking and turn signals. Funny, trying to diagnose this morning, I disconnected the blue wire out of the switch from the brown "hazard" wire in my wire harness. Ironically, it did not change the behavior, and my hazards still work! I think that the switch takes care of the hazard function.

So, here's how I'm hooked up:
Function - Harness wire - Switch color
RF TURN - BLUE - GREEN
LF TURN - LT. BLUE - YELLOW
RR TURN - GREEN - BROWN
LR TURN - YELLOW - ORANGE
Parking lights - BROWN
Brake Light Switch - White - RED
FLASHER - PURPLE - BLACK
HAZARDS - BROWN - BLUE (disconnected this today, no change!)

Any help would be greatly appreciated!

Re: Turn signal issue, new harness, old aftermarket switch.

BTW, I do not have any of the turn signal indicators hooked up yet! Doubt this effects above function, but if anyone knows of good lights that fit my aluminum gauge panel, I want indicators. I need two green, and perhaps either a blue for high beam indicator, OR red for a dummy light, if my alternator stops charging!

You can also see that my Autometer speedometer has failed! It failed with about 500 miles on it! Now it randomly shoots the needle all the around, until it hits the odometer reset, and will get stuck in random places. Periodically it will show correct road speed. Even when its malfunctioning and indicating well over 120 MPH, the odometer function works properly. So, there is some disconnect inside the speedo! Anyway, thats another issue, for another day!

Re: Turn signal issue, new harness, old aftermarket switch.

I'm thinking that my blinker switch may not actually be grounded to the steering column. That may be part of my issue. Though, I feel like the rear blinkers would not function properly, if that were the issue. I'm starting to wonder if I may have an internal issue in my switch.

Thumbs up Re: Turn signal issue, new harness, old aftermarket switch.

Those switches are notorious for failure. I have bought ever brand you can think of trying to get one that works well and they all end up failing after a while. Some not even new work well.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
