So what do I do about this?

 

This sensor is above my motor mount on the RENIX engine. What does is do and how am
I gonna put it onto the newer engine without the hole in that engine

 

That's the knock sensor

 

That's the Coolant Temp Sensor.
You need to remove the 5/16" square drive plug in your HO engine and install it there.

Cruiser’s HO into Renix Swap

This swap is easier than some will lead you to believe, generally those who have never done it. Those of us who have done it, like myself, will share with you the things that need to be done for a successful swap. Just think of it as swapping in a long block.

The HO and Renix have some differences but none that can’t be overcome very easily.

Any HO engine from an XJ or ZJ through 1999 can be used. One running change was that the rear of the head was no longer drilled and tapped for the temperature gauge sender beginning in the 96 model year. The sender can be relocated to the threaded hole in the thermostat housing taken from the HO engine. You’ll have to extend the wire to that location. Some brave souls even drill and tap the HO head for the sender.

You will be using the intake and exhaust manifolds from your Renix, along with all your sensors and wiring. Since the intake ports of the HO are slightly different, you use the Renix gasket. Exhaust ports are identical.
You will need to use your Renix distributor as it is different than the HO because they use different fuel management systems. The flywheel or flexplate from the Renix must be used so your CPS gets the correct signals. The valve cover from the Renix allows you to keep your CCV system intact and requires no modifications.

The HO block will have a plug in the coolant galley on the driver’s side of the block, closest to the front, which needs to be removed so your Coolant Temp Sensor can be installed in it’s place just as it is on the Renix. It requires a 5/16” square drive or a modified 3/8” drive that has been ground down to fit. Do this before installing the engine.

As for the knock sensor, which is located just above the oil pan on the driver’s side of the engine about mid way, all the blocks I’ve seen are threaded for it. If not, I’ve heard they may be drilled but not tapped. Tap the hole if that’s the case.

Really? Your Renixes are weird. I'll shut my mouth now.

 

Simple misunderstanding. The knock sensor has a plug exactly like an injector.

"As for the knock sensor, which is located just above the oil pan on the driver’s side of the engine about mid way, all the blocks I’ve seen are threaded for it. If not, I’ve heard they may be drilled but not tapped. Tap the hole if that’s the case."

 

Gotcha thanks for all the help I couldn't get this done without the knowledge of cruiser to guide me along the way 👍😁

 

Oh and speaking of the knock sensor, I heard that if I don't tap the block out for it I can simply plug it in and zip tie it real tight to something so that it doesn't move around and I should be fine. Not sure if this is a true statement or what

 

It's not threaded? (the hole in the block). I'd tap it, even poorly done would work better than zip ties.

 

I bet it's tapped anyway. Let us know.

 

My '99 block hole is threaded. But it's rusty. If it never had a knock sensor installed you'll have to de-rust the hole before attempting to install the sensor.

 

I've never heard of one untapped.......

 

Trust me it is not tapped I've checked haha

 

Post a pic.

 

I'll be working on it tomorrow so I'll show you but I know this sounds like a stupid question but i don't remember what all wires go to my starter
