'95 3vz engine swap into '88 1st gen

I just purchased a 1st gen '88 4runner and the previous owner installed a '95 3vz engine in it. The original engine harness and ECU are still in the car but not everything was switched over to mate with the original harness. The items that I still need to replace are the distributor, fuel injectors and knock sensor. It looks like he switched over all the other sensors already. The distributor is pretty straight forward a I am just going to purchase an '88 distributor but I was wondering if I can just relocate the knock sensor so I don't have to tear the engine apart? Or, do they sell a pigtail converter to connect the '95 sensor to the '88 engine harness. I don't want to cut into the engine harness. I actually have the same question for the fuel injectors. The connectors don't mate with the '95 fuel injectors so i was wondering if someone sells a pigtail jumper to connect the two. Thanks!

 

The fuel injectors are easy. I changed out the plug ends last Sunday. We had to use two separate wiring harnesses two get to 6 plugs because 3 of them were broke. Just look into the plug and take a pick or eye-glasses screwdriver and lightly release the pin lock while gently pulling out. This is on the 95 engine into a 87. We had it running that knight.

 

This is why this forum is so great. I didn't even think of that. I have the connectors that mate to the '95 fuel injectors so I will try to remove the pins from the '88 connectors and install them in the '95 connectors. Thanks so much.

 

It took about ten minutes to do. Practice on the ones being replaced, so you can really F them up and get the hang of it. be sure to note the wire location. You don't want the injector sucking fuel, LOL! I don't think that can happen? Just put a dot on the black wire location with a sharpie.

 

Will do. Thanks.

 

After further research, it sounds like the '88 fuel injectors have a different internal resistance than the '89 - 95 fuel injectors so I will need to purchase '88 fuel injectors since I have the original engine harness and ECU.

 

Good to know. I would have changed the injectors. The owner of the truck did not want me to. He didn't want me to touch the engine because,"it ran like a top." So I changed the the plugs ends. Now I wounder what kind of a problem they will have. The engine started up and ran, but how good, lol! I guess time will tell.
