Im doing the obd0 to obd1 swap to my 90 teg and i got the jumper harness that makes it plug and play, basically im kinda stumped with the wire setup, theres a loom of extra wires coming off of the jumper that needs to be wired up and i really dont know exactly where they go. theres like a half asses instuctions with it but it really just tells me things i already know. If n e one has done this wiring or know about the wires could help me out id really appreicate it. im doing it tomorrow morning so asap would help alot. Thanks

i believe they go to 4 wire o2 and vtec. its been a while since i went from 0 to 1....

bump all info is helpful thanks

thanks man helped alot doing the swap this morning so well see how it goes, its pretty strait foward but it would be a hassel to do look up all the pin outs and see which wire goes where lol thanks man

no problem and good luck, i'm getting ready to do this too in the next week for the gsr swap in my 91 DA

this might sound dumb but im just making sure you know that you cant use the obd0 dizzy when you convert over to obd1. depending on what motor you have you'll have to get the obd1 dizzy for it. it wont just wire up either you can get the jumpers on ebay that let you just plug n play but you can also cut the wires and put the obd1 plugs on. the wires are the same color just hook them up i recommend soldering n shrink rapping them. All the wires are the same color but there is two whites. just twist them 2gether n if it doesn't start reverse them n it should fire up then solder n shrink rap those ones too.

Yeah i did this this morning.....not a good outcome.. before i touched n e thing everything was fine no check engine and car ran fine...after i did the entire conversion i turned the car on and i was shooting a 9 and a 21, 21 is vtec sol. thats easy ill run new wires but the 9 was cylinder sensor??? i didnt think my engine even had such a thing if n e one knows whats that all about id apriecate it alot thanks

if u use a jumper y would u need to change the dissy?

seanbev24

because an obd0 dizzy can't be used with an obd1 computer.

to the OP, i think that cyl. sensor might be in the distributor, do you have it wired correctly? you did switch to an obd1 dizzy, right?

and thats the easy part

ray on boost

well that means I need to get a dissy by this weekend. I don't need any problems wit my swap.

xsi90teg

yeah i got a brand new obd1 dizzy might be wired wrong ill check that this morning sometime

seanbev24

could we get some more details? what engine and what ecu are you running?

ray on boost

yea when u find out how to do it if u could explain i would be greatful

This link shows the locations for the obd0 and obd1 distributors...

They make an adapter harness for obd0-0bd1 dizzy, but I feel like it's a total waste of money. The best way would be to just de-pin your obd0 plug and stick the pins into the appropriate places in the obd1 plug. I'm almost positive this works. If you don't want to do it this way (or if for some reason it won't work) just solder and heat shrink the wires. I wouldn't butt-connect dizzy wires personally.

yeah i had 2 wires mixed up and now its not throwing the code but its stll running like pure crap, i was talking to one of my buddies and he said his one friend did this a little bit ago and he had the same problems, he said it was his injectors he had to change to obd1 injectors and get rid of the resistor box, well my next question is how would i go about deleting the resistor box?

MHBb16CRX

I thout all U needed was the Jumper, OBD1 dizzy & ECU? or am I wrong? I'm about to do this swap. I want to hear from U guys first before I start.

seanbev24

i don't see why the resistor box would have anything to do with it. you should be able to keep your obd0 injectors and use the resistor box, or switch to obd1 injectors and remove the box. the ecu shouldn't have anything to do with this from my understanding.

this is why you wire the resistor box in when using dsm injectors on an obd1 car, the ecu doesn't care it's all about the type of injector.

MHBb16CRX

sweet. I got this then.
I'll post a write up. the being of next month. when I got everything run on my car. so that way I can tell the difference between OBD0 and OBD1 in performance.

peace
