Can I take a digidash from an 88 gl10 and put it in a 88 gl10 that did not have the digi dash?? Is wiring the same or would I need to swap harnesses as well??

 

Same question for the "computer" that resides in the center console.

1) If they are both GL-10s, they should both be digidashed. That is part of the GL-10 package

2) The wiring is different between digi and analog, but with the FSM, some cutters and lots of time, you can do it.

 

3) Trip computer - see answers 1 and 2
