[QUOTE="Bebop, post: 734480, member: 5925"] Electrical blahblah I've always wanted to keep the Holley ECU in a waterproof enclosure. I heard they weren't very pressure washer friendly. I had an old ammo can laying around and thought it would be perfect for this. ECU and PDM are in it. The chassis harness goes through a Deutsh HPD20 1/4 turn waterproof plug, so I can pull the chassis harness in a few minutes if needed. I wanted to do the same for the ECU harness, but I chickened out when it was the moment to cut the 50+ wire engine harness in half. I still used a Seal-it neoprene "waterproof" firewall grommet.

Changed all the power wires to go to the PDM, moved a few sensors and added some (trans temp and NOS circuit pressure). Gauges will be on a small digital screen before I can afford a big Holley dash. I used a double circuit kill switch so I can kill both the positive and negative circuits at the same time.
