The computer harness's would have to be repined,not real easy. Your best bet is to find a 87 harness,again not so easy. The tank is the same ,the sending unit is different, it will read backwards.I don't think the I/P will stop it from starting.most of the senors will be wrong on the 88 motor for it. I did the opposite of what your doing a while back.

So the harness on the 87 is in fair condition and the 1988 is like new its just that my 88 in my prifile pic was stolen bent frame and core support pretty bad.but all im doing is swapping engines their both 5.0 i hope it will work out i really dont want to sell these cars.cant i just use the 88 ecu and harness.???if i do that i may as well take out the whole dash and get rid of all thedigital bs i hate it but oh well i guess ill see what happens and look into it some more

If you got the 87 harness your all set. Just use the coolant and oil sensor from the 87 on the 88. Should be plug and go.
