Mine are all bundled up so I can't tell you which colour.

The OEX codes for my alternator are wrong. I had a fruitless argument with the auto sparky who installed it (he said the charts are never wrong), he was using the tacho feed wire (7v ripple) to turn the charge light off, he wired something else into the batt voltage feedback circuit so it was charging at 16 volts.
He wouldn't capitulate, so I took it home and fixed it myself.

The hitachi is 3 pins, no tach output that I found, but only had a quick look:o

Foil backed closed cell foam might be better?

lastly, if you make a decision to custom make a new rear cross member, I'm all ears :)

i was going to use what i had laying around.... but i like your idea, hmmmmm

got a replacement rear cross member in the deal so i doubt i will be making a custom one, but i would like to alter this one before i fit it up to reinforce it so i can put a home made kaymar style wheel carrier on it without the drama you can end up with..

Well done Dave....a nice old truck....aircon that works eh....wouldn't mind seeing if mine would be worth the effort to sort.

cheers
