    Tell them to upgrade to a motorcraft 2100. There are all kinds of articles on the web on how and it's well worth it. What year 4.2L by the way.

    I think I still have the adapter plate I used on mine. I'll look around this afternoon. I'm not sure how much electronics was on the 89 but have him read up on the "nutter bypass" to see if it applies. It's old enough he can probably get away without emissions testing.

    There's a guy on ebay that has sold thousands of MC2150 modified for off road use. According to a long time member here (MV3) had one in his yj and it ran like it was fuel injected off camber/uphill/downhill.
    79 cj7, rebuilt 304, YJ family "cage" , wide track axles, Moser 1 pc. rear, lockrites F/R, TF999/D300 with custom floor shifter, twin sticked, 33x12.5x15 Falken Wild Peaks
