There are a few parts of the wiring that change insulation color code, but overall there are excellent schematics and flow charts. There are some things that I also found quite odd like how the non-A/C USDM cooling fan grounds power through the coolant switch and does no use a control relay. I also noticed a few ground designs were sub-optimal when going through the chassis and engine harness on this 91 db1.
Yeah, that radiator component wiring was very interesting to me as well. When I removed my AC I did my best to mimic the factory non-AC wiring per the Helms manual. This manual always comes in handy
Sooo… which is better the factory service manual or the Helms??

They are the same. Helms makes the factory service manual we’re talking about.
Not take over your tbhread, what are the factory service manuals worth?
