Whats up H-T. so ive got my 91 DX EFsedan with a B16 swap. Currently running OBD0 and i want to convert to OBD1. i believe ive got everything i need.
-ECU jumper harness(OBD0 to OBD1)
-OBD1 ECU(95LS ecu/chipped & converted to P28spec)
-OBD1 dizzy(TD68U)
-4 wire O2 sensor?

the o2 ive got bcuz i herd i needed it. do i? what for?

also, once i plug in my ECU, jumper harness and dizzy i will need to connect my OBD0 engine harness dizzy wires to my OBD1 dizzy wires. i could just get a dizzy jumper but id rather hard wire it.

now with matching all those wires to each other, everything should work and start up just fine right? and wire "X" do i connect those together also?

ive done a lil research. just would like afew guys to confirm my info is correct. thanks everyone!

 

BUMP!!!

 

As long as each wire is carrying the "proper" signal, should work with no problem. And I believe 'X' is the absence of a wire in the above diagrams. Just follow the top chart (exact same one that came with my Boomslang harness) and cut, solder, heat shrink, wrap

As for the O2 sensor, the signal is the only "needed" connection. But without the remaining connected, you'll throw a code for the heater circuit.

 

so how would i wire my o2?

 

you dont have additional wires on your conversion harness? my phereable.net harness has like 6 extra wires..4 for o2, and 2 for something else..

 

i think it does. . . thats what i would wire it to? the extra wires on the ECU jumper?

 

yep. see if you had purchased a rywire harness by chance then you wouldn't have to worry about it. the extended wires and plugs are already there

 

ok so connect my dizzy wires as shown in the pic above and wire my 4wire o2 to my ECU jumper(that should have the wires)

correct?

 

i just said yes.. what more of a confirmation do ya need. hopefully the wires are atleast labeled, but if not you'll need to look at where they go on the ecu to figure out what each wire goes to on the o2.

 

lol. ok got it! thanks for the help!
