Im currently in the process of swapping a b16a2 into a 91 lx sedan , and I have a couple questions they shouldnt be to much to ask anyone , and I have "searched" and I have used google, and I have found a ton of info thats help me out thus far , but.. I have some **** thats screwing me up

first - my car is a 91 lx sedan dpfi i understand that i will need order a ob0-obd1 ecu jumper
the ones I have found have a lead of 4 or six?? wires that I need to wire into the car myself , are these the dpfi-mpfi conversion wires ?

second- i have converted the b16a2 down to obd1 , I do not have a b16 harness but i do have a d16z6 harness its to my understanding that i can use this harness on the b16 with no real issues ? so far everything has plugged up )

now i need to know what to do @ the chassis - engine harness plugs, do i cut the engine harness plug off and pin to a obd0 plug (or the reverse?) running the wires mentioned above on the dpfi-mpfi to the chassis-engine harness plug ?
if this is so can someone show me a simple pin out diagram and ill be on my way , if there are more steps could you please post this info

im also under the impression that i am able to use the obd0 dpfi harness and convert it to mpfi make my own sub harness and just swap a few plugs from the obd0 harness to obd1 plugs , it seems to me that there are a couple different methods and im thinking thats whats ******* me up

thanks in advance ,be light with the hate , its been about six years since ive messed with these cars and just randomly got sucked back into them

1. No, obd0 to obd1 jumper harnesses have 9 wires I believe. None of these wire's are for the MPFI conversion. These wire's are for add functionally of OBD1 cars. Vtec, vtec pressure switch, 4 wire O2 sensor, Check engine Light, IAB, & Knock sensor.

Easiest way i've found to do MPFI conversion is using a OBD1 harness. You'll want to cut away all the protective sleeve of the OBD1 harness. Depin and remove the injector sub-harness. You'll have to extended the one yellow/black wire and pin it into the engine harness on passenger side. Find a connector that fit's the driverside connector and make a pigtail. Go into the car cut all four injector wires and solder the new wires into place. Run two wires from Distributor into passenger compartment. Blue/Green and Blue/Yellow. Then follow online directions for proper wiring.

2. Use the Engine harness that came with the chassis of car... End of story! You'll have to add a few plugs maybe even change a few but much easier in the end!

If you're running an OBD1 Distributor just depin the OBD0 Distributor plug one wire at a time and pin into OBD1 distributor plug. Believe all the wires are the same color... One maybe different.

Awesome thanks for your help, so i should cut out the injector harness and wire it into the obd0 harness. Rather than swapping the large plugs on the engine harnesses ?
Ive only got one shot at this so im trying to understsnd everything entirely thanks

Don't cut any wire's from the OBD1 harness. You'll cut the protective sleeve from the complete harness. On one end of the harness you'll have a plug that terminates and is plugged off. On the same end you'll have a Yellow/Black or Red/Black wire that needs pinned into the Engine Harness Driver side of car... ( Thank I said Passenger side previously, FYI this only works with OBD1 & OBD2 Injectors) It will take the place of the Yellow/Black wire at the harness connector. The Other end of the injector harness ends with a four pin male plug... You'll need a 4 pin female plug. Find a plug that will work from the donor harness and cut it out. In the passenger floor pan of the ED cut the four Injector wires... Believe A1,A3,A5,A7. Solder pig tail into place connect injector harness your good to go from a fuel stand point!!! Then do the Distributor wiring. Not sure on specifics or I'd tell you It's easy just look it up... I know It involves B10,B12 C1, & C2! have fun!
