true dual for obd1 can it be done

I'm gonna be purchasing this one here. Acdelco with an adapter harness so no modification of the factory harness is needed.

Holy jeezus $85 for an O2 and a pigtail. A 3-wire AC Delco O2 is like $38 from Amazon. I'd rather scrap a connector off a junk harness to change the truck harness to 3 wire to make future O2 replacements easy and call it a day. I guess in the end though, about $50 for that pigtail isn't outrageous when you look at what pigtails for most stuff costs.

I hadn't ever priced them. I feel like a horses ass. You can buy the harness separate from the vendor for $25. I try to stay away from modifying factory harnesses. I figured the cost wasn't that high compared to o2s I've bought in the past for other vehicles. Here is the harness.

Hell yeah; snag that pigtail for $25 and then just get the O2 from a different source. Clearly they're trying to make a killing on the sensor, while pricing the pigtail reasonably.
