LED Conversion - snafus? Options

[mcbrems]

Hey All,

I swapped all of my bulbs for LEDs from Autolumination and/or
superbrightleds, and have encountered some unexpected issues. Replacing the
turn signal flasher was a known. I tried TimK's hack on the CF13 GL-02
flasher, and when installed and engaged, it just sat there, although the
hazard flashers worked fine (it seems to work on the same relay). I noticed
this aftermarket "LED" compatible relay design leaves out the "C" ground
pin, so I have a different one on order from Autolumination that has it.
When I raise my headlights, the tachometer dials up to 3-4K and then returns
to rest. My dash instrument lights have also been replaced with tiny LEDs
to match the originals, but they only flash once briefly when the light
switch is pulled. My blue high beam indicator is lit when the parking
lights are on, and my license plate lights never come on.

I picked up a 1974 color wiring diagram from Prospero's Garage (
http://stores.ebay.com/Prosperos-Wiring-Di...sid=p4340.l2563 ) and
noticed that many of the wires that connect to the computer are tied
together. I cut that part of the harness off and tied off all of those
wires individually (see image). I'm wondering if I need to reconnect some
of those wires to preserve the original circuit path.

Does anybody have similar experiences? Also, is there a good source for the
factory color wiring diagram (Prospero's diagrams do not give terminal
designations for any switches - i.e. 56A, 56, C, 32, etc.).

Much thanks for any help.

(I was informed by Mikey at 914Rubber that there is another markb, so from
now on I will be:)

I guess it makes sense that many of the wires I expected to be hot when the key is on - are not. The reason is the 2 red primaries coming directly from the battery are feeding the circuit board, which then decides where to send 12v when the ignition is on.

Looking over my diagram, I see you were correct about the blue wire. It is there to send 12v from the circuit board to the alternator light in the speedometer.

The coil wires are also run by the circuit board, and would be part of the engine harness, which I'm not using.

More digging to do.
