i have a 98 four door sitting here pretty much prestine but i bent the subframe and the headgasket peaced out on me...but...i got a 95 hatch with the same y8 in it just been switched to obd1 for the p28 ecu i believe...am i right??? the hatch has been hacked and botched up over the years..memphis sounds car/autocross...now turned semi streetable again...so the problem is being that the wiring harness is fallin apart in the 95...is there any apadter or any way i can use the engine harness from the 98 and reuse it in the hatch??? make sense?? dumb question??? reason being the hatch runs fine just has no ext for the o2 sensor and that the thermostat and cooling fan along with the vtec are not working and has been botched up and what not...someone please give me some solid over informational advise on how i can get the hatch back to useable standards!! pre thanks too all who reply.

 

thanks bud but its already converted like that and the harness is falling apart...i want to know if there is an adapter for my 98 harness to make work in the 95 with a p28 computer

 

Nope. The '98 is a 1-piece harness, that goes from the engine to the ecu. Where the '95 has a 2-piece harness, that goes from the engine to connectors at the shock tower and then those connectors to the ecu. The ecu plugs are also different, but there are adapters for that. In addition, the part of the harness for the ecu also has connectors that plug into the under dash harness, which are also different.

 

yeah i started investigating that but thanks for the input...where can i find a replacment harness for my my 95 car preferibly new.

 

Depends on your budget.

Majestic honda?

They can be had used in good shape...

If you really want to get ritzy they make custom tucked mil-spec harnesses Chasebays and a couple others make them.

 

damn idunno bout all that someone was attempting that move already but failed misserably and i just wana drive the effin thing haha but thanks ill look into....ne one know how the vtect and thermo and coolin fan shoul be wired ...

 

Where is your harness falling apart in the 95? If the engine harness portion is falling apart, get another or fix it. If it's the chassis harness, well, good luck with that. That's one gigantic harness that connects from the end of the engine harness at the shock tower, goes in to connect to the ecu, connects to the climate control, cluster, everything. It's literally two pieces in the whole car, aside from little subharnesses for the A/C and maybe other stuff like that. It's not just pulling it out either, it's clipped into the car pretty well, it takes a lot getting that bugger out.

Wiring the VTEC in has been covered many times. Thermostat and cooling fan should be wired together. Some people just run a switch to the dash and turn it on manually. You could run a temperature sensor with a thermocouple and have the sensor pop your fan on.

 

i see...yeah the chassis harness is ok but the connecters are falling off the engine harness. and i cant seem to find a wiring diagram on how to run the thermostat and the cooling fan all together...

 

can i put it on a switch in my car...where do i pull power from for the thermo...where do i pull power from for the fan...how can i switch the cooling fan to kick on with the thermostat...how can i tell if it all is working...lol im lost and not finding any of this info easily...thanks for responding!

 

The thermostat does does not run on power. It opens and closes depending the temperature of the coolant.

You can force the radiator fan to run by jumping the 2-wire connector for the fan switch on the thermostat housing. But I don't recommend that you make this a permanent fix.

What exactly is the problem?

 

This is the continuation of this problem.

Buy a used Z6 harness and run that. Problem solved as long as your firewall harness is good.
