I have the Holley Dominator setup (not the HP). I would like to utilize a windeband sensor in each header since I am turbo. My question is. Do they make a harness for it that plugs in? Do I need to do that since I run an external AEM wideband sensor. Or Do I need to run just one?

Any help would be awesome.

Thanks.

The basic dominator main harness has a wideband connector in it and the 2nd channel wideband harness (possibly the 4x4 connector) is a direct plug and play for the second. Use their sensors, its a snap.

So is there a link to this or a part number? Can I run dual O2s with it?

incorrect...the 4x4 is Just 4 ins and 4 outs... nothing more.. cannot be used for a 2nd wideband


the second wideband is part of the J2 Connector

you need this one

So my question is do I really need it? or do I just tap a hole for the one wide-band that I did get with the kit and use that for the Holley and the AEM for added security.

Naturally aspirated... probably not a problem to only have one wideband....
but its nice to have the 2nd one, and its not that expensive.

you will see a more consistent and smoother fueling when using 2 widebands.

Yeah, was too lazy to look for sure on my phone.
