the 1988 harness ***IS***  a bit different, this is why there is a dedicated 1988 EVTM.
reference links to the 87 EVTM and the 88 EVTMs in my signature.

your 87 chassis has climate control  .......(answer questions below)
- does your 87 chassis have **FULL*** electronic instrument cluster or just a digital speedometer with buttstuffog temp and fuel?


this should get you started
