Ouch, as in camshaft timing?
I’m sure someone here will help you get some salvage value
Maybe good to keep Those jeep computers could get hard to find down the road. Who knows
Not so much. Yeah, I watched that several times through trying to see where they mounted it, bu all that they do is mention the installation.Holley has a pretty extensive video online about the install on a CJ, maybe it weill help answer your questions.
I do have a sensor in that location. I'll need to look at it again when I get home tonight. Size and thread type, it looks to be a match from what I remember, but I'll confirm later this evening.Mine is a 258 manifold 84 vintage it should be in front of the carb location
There is a temp sensor there already attached to a bunch of wires you don't need.
Wondering if the 81 was pre-smog and may not have needed the sensor in the first place.
Also i found that the Loom is more like 2 looms - one for the original emissions wiring and one for the emissions wiring. You just need to split them near the bulkhead connector. The computer wires are the only things that needed separating on mine.
Finger pointing at sensor.

The original sensor in that location is the coolant temperature override switch (CTO) which is in part what controls venting of your charcoal canister and your EGR, and should still be used in the case of an EFI install. There are likely vacuum hoses coming off of it. There are several other ports of equal size on the standard 4.2 intake, you may have to pull a plug to install your temp sensor. Alternatively, there are a couple ports of appropriate size in the block, about halfway down fore and aft on the driver side. If yours are too small (on the block) then I'd guess you might need a different sensor, but check for others on the intake.
Yep, right on all accounts!View attachment 77304
This sensor here is what I was thinking would be the temperature sensor/switch. As you can see here, it is an electrical connection only. The sensor to the right looks to be a vacuum connection. Would THAT one be the CTO, if vacuum hoses connect to it? Would the sensor I am pointing to be the location for the new temperature sensor that Holley provides?
Thanks guys for all of the time!
COOL! That was my hope! Now, I know exactly how to move this forward. Thanks very much!I believe you can just pull it and replace with your sensor, yes.
This is a manual transmission. Not sure about the CA thing. My son got it from a women out of Seattle. How can you tell?
I installed the O2 sensor in the existing port just after where all of the exhaust comes together but just before the connection from the manifold to the exhaust pipe.
