Didn't read the whole post... I had 2 gauges already and just added the oil press, and my wiring was done through the fender. I redid the whole wiring because I wanted a cleaner look. Now, all that's left is making my custom pod.
In another note, I think I read somewhere that you added wiring for relocating the clock. Am I right? When I saw it had 8 wires, I thought about just leaving it unplugged. I pulled on the clock harness and managed to bring it down to the shifter trim without adding wiring. It's pretty tight, but it reaches.
