3 temperature sensors??

[camp9]

I'm putting in a mechanical temp gauge in my 1986 M1031. While looking over the motor to see if there was any other place to tap into the head other than where the idiot sensor is, I noticed a plug with with a single wire going into the drivers side head on the front of the engine, just under the alternater, and another one on the back of the passenger side block. What are they? Thanks,

Front driver side is idiot light, back pass is cold advance/high idle. And the one on top of the driverside is the gp coolant sensor.

Thanks uscgmatt, I had thought the idiot light was the one on the back by the oil preasure sensor, that help,

I would love to put gauges in my M1009

Gauges are on my todo list in the future.

Determining where to put sensors is my biggest hang up, otherwise I would have already done it.

I put a temp gauge on my 1008 but thats been at least 10 yrs ago, can't remember what I used fo rthe output point. Now I got a 1009 and would like to do the same as I have a complete gauge kit. Where would the best place to put the sensor? Would I have to remove an existing sensor?

There is some good info when you do a search on here, if you type in the right words I'm going hook the temp in the one by the oil pressure sensor, and I bought a T to put the oil in so I have both gauge and idiot light. I put a push button in for the glow plugs and by passed the card, so the temp gauge placement in that spot should work. I'm planing on getting it in tonight, I'll let you know how it worked. By the way, there is also another oval shaped plate that is the counter part to the place with the sensor on the back of the motor. On mine it's under the dip stick for the trans. I have a fuel injector line that goes over the top of mine. I see from other posts that guys have taken the blank out and taped it to thread in the sensor.

I'll post pics of mine when i get home.

Heres two... There'a trans temp gauge in the empty hole now to match. Didn't drill a single hole and all the idiot lights still function too!

 

[camp9]

Ya, a trans. temp gauge would be nice too. Looks like you got it set up nice.

 

[DIESELGREEN]

It does have a trans temp gauge, just didn't in that pic. It has a derale extra deep trans pan on it now too.

I got them installed and all is working good. Temp going down the road is about 190f and oil pressure is about 45 going down the road and 20-25 idling. I attached them with some automotive goop to the dash.

My oil pressure is like 40-60+ higher when cold, does this sound too high? I have the sensore at the valve next to the radiator

 

[camp9]

Sounds like the same as mine. When cold it was pushing 60psi.

Do you have any picks where you taped in to the trans?

if i'm not mistaken, u can change out your idiot light gauges for a true set of gauges. replace all the idiot light senders with for real ohm style senders and not have to change out the wiring at all. we did it a few years back to a m1008 and never had any problems. i have a few extra civil gauge sets if any bodies looking to change over.
