LED Conversion - turn signal indicator problem

Chip

I pulled the "very early" diagram and see that the "turn indicator" in the
tach is wired completely different from late models. I do not see the need for any
modification to the wiring to get it to work. The diodes and pig-tail should be
unnecessary.

Unlike the late model, the indicator bulb, in the tach, does not ground using the blinker bulb filaments; rather,
their is a red wire carrying 12V to the bulb and it is grounded through the
orange wire leaving the indicator bulb going to the flasher. The flasher appears to have a relay
grounding the orange wire to the exiting black ground wire.

Have you tried the indicator light with the wiring unaltered?

Chip,

Remove the red and brown (orange?) wires from the turn indicator bulb socket and cap these wires. Install the diode and ground pigtails to the indicator bulb socket as shown in the instructions. Add two new wires to the remaining ends of the two diodes. Extend these two new wires to the molex connector for the hazard warning switch. Splice one wire into the light blue wire at the molex connector, and splice the other wire into the light blue/black wire at the molex connector. This should solve the problem.

Chip,

You can also try the PanteraPlace conversion with a relay.

I got the Space City kit and PE (Jon Haas) kit for the brake lights. Both are super simple installs, both work as advertised. An objective review -

Space City kit is a standard base bulb, with many 'radial fire' LEDS gang-mounted around bulb area. (Photos coming.) Basically occupies same space as original bulb.

Pantera Electronics kit is a composite 'panel' of LEDS, evenly spaced across board, which essentially 'fills' brake light housing.

Space City kit disperses an 'oval' light pattern within the brake light well, filling perhaps 70%-75% of the area with light.

Pantera Electronics kit fills brake light well completely, evenly.

Both kits install quickly.
Both kits have FASTER reaction than incandescent. (I tested both.) This alone worthy of consideration by anyone on this board who'd consider additional stopping/warning as a bonus.

Bottom Line: Pantera Electronics kit, in usual Jon Haas fashion, is expertly engineered and Pantera-specific. It is expectedly more expensive.

Space City kit accomplishes task with non Pantera specific application, yet with marginally lesser light output.

* Space City kit came with blinker bulbs. My flasher did not require additional wiring, blinkers are both faster AND brighter. Another bonus.

I would not go back to incandescent in the car. Would advise owners to take a look at your current, puny brake light output. Also reconsider illumination speed. Get the LED that fits your desire and wallet.

A third brake light helps brighten up the back too.

I got one like this: http://www.scottlandyardspares.com/light16.htm

There are versions that tie in to indicate turns or hazard.

I mounted it on the underside of the sugar scoop. It's hollow so I tucked the wires inside and snuck them down to the multi pin wire connector for the back harness and picked up the brake light wire.

I'm sure you could get one mounted just inside the decklid opening if you don't have a sugar scoop spoiler.

It's usually the early '71 cars with the 4-wire flasher that require some additional wiring.

Thanks. I spliced to the light blue & blue/black, ran the ground and it works great!

Quick easy fix!

Thanks again, Chip

Chip,

Great! That's what I did on mine with the 4-wire flasher.
