Re: \'91 ECM
I bought a thrashed out 4wd 88.5 because I had a really good condition 92 2wd. You'll need both if you want to do the swap using the stock carb. I spliced the eng/ECM wiring from the 88.5 to the 92 wiring harn. I also used the 88.5 instrument cluster. I modified the carb after doing the whole swap to run off only a single power wire(I was tired of having my computer tell my carb what to do) I then pulled the 88.5 part for the ECM out of the harness, with all of the sensors, and put it all into a small metal box that I can put in and take out with the stock(ECM driven)carb. If I ever have to pass an emissions test, it will be very simple to put the box and the carb in. As far as the 4wd, I just got around to doing that and it took me about six hours. The only real problem I had was the rear driveshaft. The yoke bolts on the 2wd were 14mm and the 88.5 were 12mm. I just slid the front yoke of the driveshaft off, lined up the 12mm front yoke from the 88.5, and slid that one on. If you want any wiring diagrams(modified) e-mail me. I have a bunch of notes and head scratching doodles, but I can compile them into something you can read (they are written in
confused-ese right now). Now I have a one wire dist. and a one wire carb. I want reliability, not high tech. I four-wheel alone, so I don't want to have to walk back from nowhere and leave my zuk to the vultures. I was four-wheeling in 2wd before now, now that I'm 4wd, I can be a little more zealous now! Also, I almost forgot, the fuel tank needs to to be swapped along with the int. man. and you'll have to use and electric fuel pump with regulator. This is why I say buy a parts zuk, it will also give you many spares.
