Rundown: 89 crx dx. b16a1 obd0. obd1 dizzy and obd1 p28 ecu with hondata s300. Did a wiretuck and cut the obd0 plug off the harness. Now im wiring the obd1 plug on.

1)Where do both my 02 sensor wires go? I have 2 o2 sensors and each has one wire. The obd1 o2 sensors have like 4 wires dont they? So which pins do my o2 sensor wires go to?

2)Pin A20 goes to evap purge control solenoid. Do i have that solenoid on my obd0 b16?

3)Pin A25 is IGP2 Power Source.. Where do i get this wire from?

4)Is there an electric load detector on an obd0 b16? If not do i just leave pin D10 open?

5)Pin D1 is voltage backup.. What is that? Just a 12v ignition source?

Thanks for reading.. Please answer if you know.

She needs your help.. And im almost done with this blunt. Time to wire, and i need some answers.

thank you in advance

-A25 and B1 both go to main relay can be put together
-ELD is in your under-hood fuse box which im assuming is now on the passanger side floor
-D1 there is another white wire with a green stripe that it connects to in the car

the other to I can help you with since my motor is ODB1 and a single cam

And by main relay do they mean fuel pump relay? Cuz thats the only other relay i found in the car. Thats pretty much the only part left. Wiring the fuel relay.

Still have to split loom the bay but im tryin to finish it tonight.

A25 and B1 go to the MAIN RELAY which is under the dash on the driver's side they can be connected to each other at the ECU as they go to the same pin on main relay (at least on mine they do)

Also what gauge wire did you use for your battery relocation?

ef dino

Tsunami 4 Gauge to a tsunami fused distribution block to two 8 guage tsunami wires. 1 goin to starter and other to fuse box. Ive been a car audio installer for about 4 years.. so top quality wire is all over the place in my garage.

4 gauge is kinda small. Should have went 0
and 4 gauge to starter!

ef dino

Stock battery is 4 gauge and stock starter is 8. I didnt feel the need to go bigger. Unless i was running an amp or something. Everythings drawing the same voltage. Guess it couldnt hurt though. Wensdays are slow, maybe ill switch em then, thats like a 10 minute project.

BUMP. Where do my 2 o2 sensor wires go to on an obd1 ecu plug?

crx_si-r

its simple. for your 2 o2 sensors....you dont use them. since obd1 cars run a 4 wire o2 sensor. and im assuming your gonna be using a obd0-obd1 jumper harness, that harness will have the wires for the 4wire o2 sensor. follow the instructions provided and then youll be set.

ef dino

Now i see you missed the part where i said im a complete dumbass and absolutely love to make things harder for myself, so i cut the obd0 plug off.

Dont even comment on the part where i cut the plug off. Just let me know what to do with my two 1 wire o2 sensors.

IndySporty

use the search function and type in obd1 pinout, then follow the pins on the OBD1 ecu pinout and wire them up accordingly

clean bay!!

Thank you! working on converting the fuel lines to stainless and eventually a shave and paint job.

im glad i came across this thread.. would too big of a battery cable guage start blowing fuses? I thought i read something about that a little while back but I wasnt sure.. I just relocated my battery. and I used either 4guage or 2 guage cable thats why I was wondering.

zccr-xsi

what kinda of intake tube is that?

Yes true, but in stock location!
Longer the run=more resistance ,which=larger cable needed

team2dcrx

alright pull out your one wire 02's and use 1..... 4 wire 02
and then use this
