I am converting my 91 crx to obd1. Got an Evasive jumper harness and need to know which wires are for the new 4 wire o2 sensor. I have a plug from a 97 EK with a green/black, black/yellow. black/white, and White wires. Which are which and where do they go?

TIA!

Also, does this picture I found have any validity?




also, need to know which wires are what for the distibutor so I can make my distibutor jumper or just solder obd1 plugs to my harness.

 

you shoulda called rywire. theyre great to deal with and could have supplied you with everything you needed.

 

amen to the man above

 

im going to solder obd1 plugs onto the harness for the distributor, so I need to know the wiring. I dont want a big, ugly jumper in my engine bay.

Does anyone have some relevant, accurate information?

 

you don't need to solder any wires into your harness. just de-pin the obd0 distributor plug and pin the obd1 plug in. the only one that's a little different is the 2 wire plug that goes to the distributor. i cut the obd0 plug off and wired in the obd1 plug. just the 2 wire plug though. here is the wiring diagram:


There is some de-pining and soldering at the ecu though. i'll post that in a sec.

 

Here's the rest of it, be sure to use the diagrams on this site to do your pining, de-pining, and soldering for your distributor wires. if you want I can post pics of what mine looks like. just let me know. http://effinmotorworks.com/Effin_MPFI_swap.htm

They go to what the instructions with the jumper came with, every jumper usually uses different colors so it should have come with instructions. And either depin the dizzy plug or get a jumper for it because it will look like crap all soldered and taped up

 

dizzy plugs wont look like crap soldered and reloomed. I know how to solder. The instructions with my jumper did come with distributor wiring and o2 wiring (for the jumper itself) but not my plug. I didnt realize it had the distributor wiring before making the post...I need to know which wire colors on my o2 plug are what. the 97 ek plug with:

wht
grn/blk
blk/yllw
blk/wht

 

this is the wiring for mine, its not the same brand jumper harness but it might help
