1. yes i said cadillac (slang)

2. no you cannot have my $300 Honda o2 sensor for $10....it's amazing how much honda wants for these rare VX 5wire sensors...sorry bro

3. i still need some info on how to wire this 4wire o2 sensor into the p75 using LS engine harness and civic VX chassis harness...thanks

Its impossible to use that sensor on a P75 ecu unless u get some hardware to convert it all into a signal the ecu will be happy with, which costs about $100. diy-wb.com , tech-edge.com.au

okie, i found the setup, the yel/blk wire needs to get routed all the way to the ecu, at least i found it easier to do it that way, then it gets t'd into the yel/blk on A and the yel/blk on B at the ecu. The other 3 wires you can use ones from the VX harnes, you'll have to make your own plug setup though, or just hardwire them. I bought a 4 wire waterproof wiring harness from pepboys, both the male and female then rewired both sides at the old plug area.

Okie, for 4 wire the wires are this:
Grn/Wht 2
Wht 1
Orn/Blk
Yel/Blk

for 5 wire they are:
grn/wht 2
wht
wht/blu 2
orn
orn/blu 2
yel/blk
blk 1

Okie for the the other wires, take the 5wire yel/blk and that goes to the 4wire orn/blk, grn/wht 2 is the same on both 5wire and 4wire, and orn/blu 2 is the wht1 for the 4wire o2. IM me if you need any more info.


btw. the above colors are directly from the helms, some of those cables are routed inside the cable plug so you dont think, gee thats more than 5wires...

Search might have found this, but heres my notepad from my post to this. I converted my system to 4wire for a mini-me.
