Im dropping in a b18c1 into a 96 hatchback. I am using a 98 EX wiring harness. I followed the IAB wiring directions on HybridHonda website, but I noticed as I was running the wire to the IAB sensor there was 2 pins. So where the 2nd pin connect to? Is that 2pin suppose to be a ground wire or does it hook up to the ECU? Help please.

 

In my '95 the IAB solenoid gets battery voltage from the main relay (yel/blk wire) full-time. The ECU grounds the other wire to energize the relay.
