I have a 87 GN engine wire harness with the computer left over from a recent conversion I did. I have it because I ran into a super deal on a caspers new harness and decided in the middle of the project to buy the caspers and sell the 87GN harness/computer. The harness is very good condition,only the O2 sensor wire was cut to extend it bout 12" and the computer is missing the small chip(cal pak),but it does have the orig 87 big chip in it.The harness has the oval conduit and the hard plastic cover on the driv side,even has the two orig relays that are on the pass side. No corrosion on any of the terminals,very nice piece here. Selling it for what I paid for it plus shipping,,$250 plus shipping.I`m looking for a few parts yet,so a part trade would be ok,,I need long alt bolt,the "Y" ac/alt bracket,eng dip stick tube,P/S resevoir bracket,throttle cable,trans throttle cable-----thanks,,Jack
