97 5s into a 95 5s Options

[JuMPiiN]

I just want to be 100% positive that it will be plug and play. taking out the old putting in the new. I decided to go ahead and put another few 100$ into the car and make it run again, Getting it for a good price and just needs the seals replaced, new oil pump, and water pump, and of course new belts.

Basically what im asking is that it should be all plug and play now wiring needed. If theres some thats fine, But it should be just pulling the old putting in the new and plugging everything in right lol ?

as long as both motors are obd II you should run into very few obstacles

[stephen_lee]

its not.. soo swap all accesories and the wiring harness over (dizzy & oil pump are diff on the 7a between OBD1 and OBD2)

[JuMPiiN]

My wiring harness is kinda messed up.... pretty badly. And i ordered a Oil Pump, Water Pump, and a timing belt today for a 97 5sfe 2.2L. And i was going to swap over my AC compressor, alternator, possibly distributor since mine is new. I think thats all ? Not sure yet tho i should have it sometime next week.

[njccmd2002]

well remember youll be using an obd2 ecu, obd2 wiring harness and obd2 circuit open relay

so im assuming it may just be wiring..... just a matter of reppining certain wires, so that it goes well...

the engine does not have ignitor, alternator, ps pump or ac compressor

So youll need to make sure the ignitor is the same part no.

the ac compressor and the alternator and the ps pump. should be interchangeable...

dont start swapping out things you may not have too....



repining the wires to get the obd2 scanner to work

[JuMPiiN]

Well I need to use the new harness because my old one has a burned wire in it. Unless I could get a obd1 wiring harness from someone on here and just use my old computer and swap over the parts from the old engine to the new.

If someone could tell me what partsni would have to swap over to make a old harness and ecu work please tell me. I REALLY WANT MY CAR BACK. lol

[stephen_lee]

umm. with 96+ engine, harness, ECU, its plug & play.

[JuMPiiN]

So if I'm getting a 97 engine and harness it should be plug and play with my chassis harness and everything else ?

What about the OBD II diagnostics plug under the dash? Not sure the exact name, but you may need to pick one up from one of the Celicas in the junkyard. I'd hold off for now though.

[JuMPiiN]

Wait what ? lmfao. Could i just leave it unplugged

[richee3]

I can't describe it. I'm really tired right now. There's an OBD plug under the dash where you can plug in a diagnostics reader. I know it says OBD II in the OBD II cars I've owned, so I don't know if there's a different plug between OBD I and OBD II. I'll just go take a picture tomorrow and post it up and you'll be like "Oh, that!"

[JuMPiiN]

please do that lol.

if you're using the 97 wiring harness w/97ecu with the 97 engine (and the 97 accessories like the dizzy) then is shouldn't be a problem.
The OBII won't work (unless you wire it in from the interior plugs - 4 wires simple) but it's not a big deal unless you get a CEL and have to check your codes, so I would reccomend doing that.
If you use the 97 engine with a 95 harness then some things will need to be swapped over like the dizzy, egr, couple other little things, I can't remember off hand.

if you can get a 97 5s w/wiring harness and ECU then put it in.

[JuMPiiN]

Yea bro i got a 97 with a ECU and wiring harness. Just a few concerns on the wiring thats all.

[richee3]

OBD II port. Not from a Celica, but you get the idea.



I just wonder if the OBD I port and OBD II port are the same. But Dustin and Stephen both say it's PnP, so it's a 99.9999% chance that it's PnP.

[JuMPiiN]

I think i mat need a 97 dizzy, thats about all im using my alternator and ac compressor all those thing again and im getting bigger wires of course. and new spark plugs ( of course ) lol

[stephen_lee]

OBD1 and OBD2 ports are different.

[JuMPiiN]

That mean my port won't work ?

[stephen_lee]

the obd1 port will work as an obd1 port only.

you will be lacking the obd2 port under your dash, unless you source one and wire it in.

[JuMPiiN]

That's alright. As long as the engine runs and AC works, i hare TX and Louisiana heat.
