Right on Justin! I love how you took the time to map all the electronics out on some plywood to test everything, I have a buddy who did something very similar when he did an LS swap in his '70 Firebird. Granted you went to water cooled from air-cooled, mad props sir! You really took your time with this and made it right. Making the rear end removable is incredible smart from a service perspective also. Congrats on a job well done. I hope it means that a super epic Herbie road trip is in your future!
Nice ! Makes me want to keep working on mine. I did my wiring on a repurposed kitchen table, covered in cardboard, ZEN like focus for one weekend, ECU pin out diagram in on hand, sorting wires with the other... I should have labeled stuff like you did. Mine did not start, the relay had power, but I missed the wiring, (found a note, asking where do I connect this to ? after it started). Test mode, take it to ground, I needed that when I called Mick at Busaru and we got it sorted and started. Bleeding the air out (vanagon) was a pita...but so nice to hear it idle and the fans kick on and off...It's almost ready for paint...
Cip1.com for the US, or cip1.ca for Canada. Look for 15x5.5” rims. The herbie community on Facebook is also a great resource for these sorts of questions. 👍🏻
