This might seam kinda dumb to people who have done this swap b4. But I'm trying to put in an h22 into my teg, and found out today that the ECU pinouts don't match from my p75 ecu to my p13 ecu, the pinout layout isn't even closely the same, so of couse the connectors won't connect to the ECU. So what do I do? What do I do since the connectors don't fit into my new p13 ecu?

p75? you have a 95 (OBD1) integra?

What year prelude did the H22 come out of? maybe you have a OBD2 P13 ECU.. ? take some pictures.

[IMG][/IMG] It's from a 95 prelude. Trying to take a picture but I can't figure out how to upload it. I click insert image and al it does is IMG,IMG with brackets on em

MrMike

the pinouts should be the same for all OBD1 ecus.

JasonST

Here's a picture of them. The one on top is the p75 ecu. The one on the bottom is a JDM p13, they're both supposedly obd1.

JasonST

Bump! Anyone know? Plz. any help would be greatly appreciated!!!

MrMike

the top one is an obd2a ecu. The bottom one is obd1.

JasonST

Thanks for the help. My friends and my brother who recently came back from UTI told me it was obd1, though they never looked at the ecu, they just said there was a lack of sensors for it to be obd1. So does this mean i'm going to have to get diff sensors and rewire the entire thing?

all you have to do for the ecu wiring is get a conversion harness obd2-obd1 i had to do the same thing in my ek they are pretty easy to get just look around

JasonST

wow that makes things alot easier... Umm 1 more question. Do I still have to change all the wiring around? Or will the adapter make it so all the wires will go onto all the right ecu pinouts? Thanks

JasonST

Bump! being more specific. When i use the apadpter, will it put the correct wires into the correct pinouts? Or will I still have to change all the wires so they'll be in the correct ecu pinouts.. Somone plz reply! Thanks for any help.
