Need help figuring out if it’s easier to start fresh with a new cabin harness. This is what it looks like

and also can I use a harness from Eg coupe ex ?? This is just a mess under here wires everywhere I just want it to be stock as possible

 

That appears to be alarm system wiring and not your cabin harness. There may be a few places where those alarm system wires are tapped into the cabin harness, and you can likely fix those few breaks in the OE wires. Then decide if you need a cabin harness replacement.

 

Do all the car electrical components work fine?

 

Yes all components work . And I just needed up taking all that mess out and just leaving the stock stuff like the ignition and stuff I taped off and just put all plugs back and now car starts and everything . Thank you guys for the help

 

I’m having a problem with the ac compressor clutch engaging so I have check all fuses check all relays . When I jump compressor to the battery clutch engages . The person I bought the car said the car never had ac but all components are there . Everything is plugged in too. But I did notice ecu has been opened and tuned for a previous owner . Idk if the ecu will not engage compressor or not . I don’t have another ecu. I have a 98 integra as well (auto) the ecu on the integra can’t be plugged into the hatch to see if ecu is the issue or no?? Sorry for the crazy questions guys I’m not a mechanic or nothing lol just reasearch and trail and error. If anyone has had those issues please respond . Thanks again guys

 

All pretty much stock after kill switch low jack system and alarm

 

Does the condenser fan run when you press the A/C button?

 

Where the blower really sits in the fuse box there’s a little damage to box idk if it was before when he tried to put ac . The relay is still good cause it works when I sit in there can the fuse box under the hood need to be replace here’s a pic of what it looks like I also check the harness runnning in the blower box no cut wire or exposed . The motor resistor still work cuz blower works on each speed just don’t know if compressor is done ? Or should I keep trouble shooting to find out what’s wrong . Here’s a pic of the fuse box where relay for blower sits u can see slight damage to it please respond !!

This tells me ecu has been worked on or tampered with . Cuz it’s stamped with someone’s name for tuning clout

 

Yes the fan does turn on when I press the button

 

It helps to know the car info besides just EG. Year, make, model, trim and any mods yer aware of.

As it stands we don't know if yer engine is vtec or non, 8 valve or 16, or vtec-e etc.

Just seeing the sticker on the ecu doesn't necessarily mean it's chipped. Knowing what engine is being run by that ecu would be a better indication. It possible a stock Eco was sold from there and they tagged it for advertising.

 

Sorry guys . The car is 1992 Civic hatchback trim I believe it’s a cx . no mods and currently there’s a non Vtec motor in I believe it’s a y7z6 .

 

 

1) Remove the condenser fan relay.
2) Unplug the A/C pressure switch.
3) What voltage to body ground do you measure at the Blu/Red wire pin in the A/C pressure switch connector?

 

I just measured it and it’s measuring 0 V at that red and blue wire so does that mean that the pressure switch is bad or the harness is bad

 

I tried with the car on and I tried with the car off with the car off I got a zero rating but when I turn the car on I got a 0.4 reading I don’t know if the multimeter I have is correct or that I have it correctly set up like I said I am new to this

 

So I jumped a pressure switch to close the circuit and I found Found out that the compressor does engage as soon as I jump the switch so does that actually mean I need a new pressure switch and AC should be good

 

If your test was done correctly, the The Blu/Red wire or the ECU is bad.

 

[QUOTE=Whiteeghatch;52089561]when I turn the car on I got a 0.4 reading/QUOTE]

Still too low. Post a picture of your multimeter.

 

It may mean that the refrigerant pressure is way too low or that the voltage from the ECU is too low.

 

Should I try to add Freon into the system before I buy a pressure switch

 

Can I put a ecu from a 98 integra in the hatch to see if that’s the issue . Thank you for the fast responses too I appreciate it

 

Yes. Do you have the needed expertise and tools for this task?

 

Yes So I just finished adding one can of free on to the low side and the reading is like 20psi that’s it took the whole can .. but clutch did not engage . Thank you for responses too . To follow up on my question can the pressure switch be bad?? And cause the compressor to not engage again. This car has been tampered with as far as wiring in cabin as you seen in pics but all that is back to stock now and everything in car works as it should ..
when I jumped the switch clutch did come on and stayed on but ac wasn’t blowing super cold ?? So I’m leaning more to what u said about free on

 

Please post both the low and high side pressures while you hold the engine at 1500 rpms.

 

I wouldn’t be able to do both side I have one of those gauges were it’s just to add free on I found a stock ecu I’m going to buy and try that I guess . But like I said before the bad pressure switch cause the compressor not to engage . ?? If I replace that can it fix the problem and do the pressure switches go bad ?
