i'm actually getting ready to design a sheet-metal dash for everything because i just removed mine along with all the heater/AC/blower junk...
i know the right book would tell me which wire is which, i didn't really think it would be worth the hassle. i was almost thinking of just re-mounting the original cluster.
heater control box is going way up against the firewall because the Only thing i'll ever use it for, is checking codes. and the traction button is tied in with the cluster(theres another post about how i set the tracion default to off)
so all thats left for the new dash is 5" autometer/shiftlight, trunk button, digi cluster and the headlight/dimmer switch. then i have room for all those extras, no more "idiot-lights"!
