ok i recently purchased a new honda o2 sensor from someone here on honda-tech, an obd1 4 wire prelude one. i got it for a great price and stupid me, when i saw "obd1" and "4 wire o2" i PM'ed the guy so fast to buy it i didnt even read it was for a prelude. i went on hondaautomotiveparts.com and checked it out and they had the same part no. for the prelude VTEC as for the del sol VTEC (both obd1) so i figured id be alright so i get out to my car today (ls/vtec in a 92 hatch using the stock VX harness) and i notice the o2 sensor isnt even a direct plug in. my question is, is there something im missing, will a prelude o2 sensor be the same as a 4 wire integra one, or should i just cut the connector off and run the wires straight to the ECU? (i was always told ******* with o2 wires was not something you wanna do.) Thanks everyone.

 

****, no wonder.it was for a SOHC prelude. im so fucked.

 

anyone have a broken OEM o2 sensor that will fit my car they wanna sell me so i can hack off the connector?

 

i have a broken one. well it isn't broken its just that 2 wires were ripped off. it came like that with my h22 swap.

 

All honda/acura 4wire O2 sensors are the same. Some wires are longer than others but will work on any honda/acura with 4 wire o2. You have a vx with 5wire o2, so yours is different.

 

so guys with the vx swaps never have an o2 that plugs right in? they just run the wires somewhere else?

 

Most people with vx's convert to a 4 wire O2 during the swap. I just got a male and female O2 plug and just took the pins out of the 5 wire plug and inserted them in the 4 wire plug. This way in the future, i can just replace the 4 wire O2 by just unplugging it.

 

Thats a great idea. Which 4 wires do i keep from the VX harness?
