ok this may be a stupid question but i bought that part from Zionsville and im looking at it and not 100% sure on how to hook it up... any help?

What I did was delete the throttle body warming circuit. Used on hose to connect the head to the manifold, then a hose to connect the manifold back to the "spider hose"

Take a small wire and eyelet and screw it into the manifold (there should be a screw in the hole), then ground that to the engine (I grounded it to the engine lift hook) then connect the sensor to your wiring harness.

Super easy.

will do the safety wire no access to a welder at this point in time and ill definately make sure to get it in tight then with tape thanks

how do you know? and i am going to purchase that piece tonight that is something i was thinking about trying to do thanks!

and unfortunately i didnt get it in over thanksgiving when i pulled out the s50 i found out the m50 oil pan was cracked.

would you suggest while im in there with the new oil pan to secure the oil pump nut?

Thought it was tight, it wasn't, coolant system got pressurized, big time leak. Pulled it out, cleaned/dryed it off, hit the sensor threads with some teflon tape and really screwed that bitch down tight.

Just make sure to Teflon tape the sensor and get it nice and tight.

I use the Zionsville manifold so I didn't have to drill the head. Hose from head to manifold, spider hose to manifold. No TB circuit.

WOW, I had no idea that even existed. Pretty cool option for those running an OBD1 M/S52!!

Here's the link for anyone interested...

alright thanks, does anyone know where i can find pictures or an how-to for the tapping of the sensor?
my new motor arrived and I started prepping today for my swap goin to do it over thanksgiving weekend going to be long days of working

as stated above with the temp sensor. There's many solutions.

other than that. plug and play. The Racer's Market has a chip with good reviews to run the s52 with your current wiring/DME.

Oh! OK, I learned something. I guess the two sensors have different specs?
