Default O2 problems again. Y8 where a Y5 used to be.

97 Coupe HX swapped a 99 Y8 (4 wire o2) with a 98 EX ecu (5 wire o2)

Okay, i got all the wiring pretty much figured out, and the idle is strong, consistant, and no more hesitation.

However i still get a check light on the primary o2. My question is this, the power for the primary is tapped off of the sec o2. When this was done it was checked with a voltmeter to see if it caused any surges or current draw losses to the prim & sec o2's, none. Could this be the reason the code is being thrown anyway? What is the best way to correct this.

Kenji if you read this, would like your input...
