I'm need of some help. I did an engine swap with a Japaneese Import Engine and everything is runing ....but its running on 3 injectors. The reason its not working all 6 is due to a pin missing in(I belive) the female harness that is connected to the firewall(The big wireharness that runs to the firewall). I tried looking for my old fuel injector but had already scrap the old engine. Looking for the pics is there anyway I could add a female slot inside this wire harness or is there any adapter that could work?




This is a view of the fuel injector wire harness male pin side

Excuse the bigs pic. any help would be greatly appreciated.

 

what wire colors are coming off each plug? that's so weird for it to be missing, yet all 3 have 2 wires each coming from them?

 

easy way = hard way.
this is why you swap everything over from your OLD engine

 

Japaneeeeese

 

1 plug has a red wire with black strip and a white wire with a red strip

2 plug has a red wire with a blue strip and a white wire with a purple strip

3 plug has a red wire with a yellow strip and a white wire with a green strip

 

that's kinda weird to have 6 colors and just 3 pins at the plug. what colors are the wires on the harness-plug end?

 

At the plug end white with red strip, red with blue strip, red with black strip and red with yellow strip

 

oops i meant the one with just 3... so i guess that's the car-side plug. i'm assuming your white/x one is missing from the car-side which is the power to the injectors. ECU pulls grounds.

 

Me too. My horses were exhausted running to-an-fro the whole gymnasium wall (where the pics were projected)... but maybe I got ALL the PIGS.

Solder-in-Solution. Its not forbidden or shameful to cut and paste wires...

 

I think thats the ground for the injector signals, they share the same one. Slip out the male and see if you can ground it. They come out when you put a very tiny screwdriver inside and press on a tab, look up the 9007 headlight swap because there is a similar technique used there.

 

I think I follow you. I'm going to look up the schematic in the manual and try your suggestion

 

actually it's a +12v from the IGN, and the unique-to-the-injector wires are individual grounds. that's why i said that our ECUs pull grounds rather than pushing voltage. one wire provides voltage for 3 injectors and the ECU is at the end of the current-flow rather than the beginning.

 

I would hook everything up and probe those three wires for 12v and see if any are hot. I would venture to guess that they will not be, in which case you can simply provide an ignition switched +12v supplied to the injectors as previously stated and all should be well if those existing 3 wires are indeed the individual grounds for the 3 non-firing injectors.
