    All you need is the pin outs for the lq4 puter, to tell you which one it is. I bought the GM Service Manuals for my truck, to tell me the rest of the wiring codes, etc. They are invaluable. Got them off E-Bay. '95, '96, '97 & '98 are all transition years for this wiring, so I don't want to guess at it for you. Each of these years wiring codes are slightly different.

    green and white is the one you need to tie into for a factory gauge but if your running aftermarket they usually tie in to one wire of the speed sensor at the tranny
