Been a long winter here this year. Haven't done any work over the winter. But here's what I'm hoping to get done as soon as we get up to a consistent 40*

1. Drop the fuel tank. Double check for leaks. Redo the vapor line. (Had some overflow issues when hot)

2. Clean up wiring. Also want to add some molex plugs so the harness can be removed. (Every connection is soldered now)

3. Get door panels finished to include speaker openings.

4. Purchase and install new steering wheel.

5. After that is complete. Get base tune and alignment.

Thanks, I'm going to connect it to the coil.  That's what I was going to do initially, I just wanted to make sure it would work that way on the RB.  I have another question that I think I already have the answer to lol...  When wiring the RB alternator, what did you do with the 2 small wires on the T plug, a yellow and a green wire i think.

A couple little things I've done so far this spring. Added power locks and windows. Here's how.


Step 1. Clean and prep door surface. post-11227-0-90197600-1371433041_thumb.jpg

Step 2. Make bracket and mount door lock actuator. Push pull rod should be parallel to factory rod. post-11227-0-79975400-1371433104_thumb.jpg

Step 3. Mount window motor. post-11227-0-79036200-1371433179_thumb.jpg

Step 4. Make sure to twist the motor leads. Make sure to put on silver clip that holds gears together. post-11227-0-21482700-1371433291_thumb.jpg

Step 5. Mount bracket to window winder. Don't forget the small screw. post-11227-0-84318600-1371433353_thumb.jpg
