The All About My 1980 Pontiac LeMans Station Wagon Thread...

[motorhead]

So on Dave's advice I tried to light a light with the ~10V present in the circuit.  And...

Using a 194 bulb-sized socket, and a 194-sized LED and a standard 194 incandescent bulb I get the following results:

1. Key On & Using the LED = the faintest of illumination;
2. Key On & Using the standard bulb = no illumination;
3. Brake pedal pressed & Using the LED = blinded Mike; and
4. Brake pedal pressed & Using the standard bulb = the sweet warm glow of a generation lost.

Looks like it is a possible ground issue.  I am going to try a jumper from the frame to the body to see if that aids the situation.

In other news I can now run a lead for a third brake light - wagons need all the help they can get.

How are you mounting the third brake light?  Just thinking that the tailgate may not be the best conduit for grounding the circuit to the rest of the body/frame. Perhaps a complete separate ground wire running back to the body/frame

I was actually going to mount an LED strip along the roofline trim behind the hatch glass.  Other guys have adapted third brake lights from other wagons (like Volvo) here in an inside mount fashion.

That should look nice. I haven't done anything LED yet. Not familiar with the ins and outs of it

Finally got the fuel pump hooked up.  I had to create a breakout harness for the fuel level sender signal and low reference wires which go back to C230 for the ECM (which runs back to the sending unit).  Totally unnecessary for a swap, but I do want to ensure total functionality wherever possible.  I also elected to run an 8 gauge wire from the BAP to the pump to carry the 16+ volts and whatever amperage is drawn.  To the credit of Spectra they used some pretty hefty wiring in the harness on the sending unit.

I also had to create a tach lead off of C105 (pin G) so that I could feed my tach, N20 window switch, and the remote starter.  This wire does not exist when using a non-traction control harness.

As always, super nice work!

I've been contemplating both a power and ground buss somewhere in the interior.  Multiple gauges, alky, tach.... too many wires and looks are unsightly

[Just a Six?]

Nice Work Mike!!

"I've been contemplating both a power and ground buss somewhere in the interior.  Multiple gauges, alky, tach.... too many wires and looks are unsightly"

Flip my glove box all the way down & I have board mounted to the back of it with 10 fused + - pins for all the added gauges etc. There is quite a bit of room back there as the Alky Control box as well with Audible Knock unit sit there as well.

Thanks gents.  I am still not as good at wiring as I would like to be...

[motorhead]

So the Hookers showed up; and who doesn't love Hookers?

I wired in a micro-relay to ground the "CHOKE" light when the cruise control is activated.  There is a diode on the signal wire to the relay to ensure that it is only listening and cannot back feed any interference into the ECM (you know, just in case).

[Charlief1]

Good grief, hookers, and wife that brings a new pussy into the house. You got it made dude.

[good2win22]

Can't wait to see that speedo pegged at 160 MPH

[daveismissing]

You can run a wire from the "Windah Terrbow" beside the fuel pump  to your power windows.
You don't race and operate the windows at the same time?

[motorhead]

Manual windows... for now.  Yeah, this thing should honk when it is finished.

[motorhead]

Finished up the engine harness, and finished looming the rest of the wiring (less the stuff along the fire wall. Next I need to pull the inner fenders/fender liners out of the donor car. Once I am done that I should be able to move along to the mechanicals again very soon.

[good2win22]

Nice progress
