With the VW bug’s front plumbing complete, I can now concentrate on the wiring. Luckily I have the complete Toyota MR2 service/wiring manual set to determine what everything is. I need to determine where all of the boxes need to be (ECUs, Relays etc.) and how to route the correct wires to their locations. The length of the harness will establish the location of each box. Did I mention “concentration”.
