I have a 90 dx 4spd Motor was trash so I got a motor from a 92-95 dx.. Im gonna use the old intake manifold and all that trany blah blah blah.. I have taken the motor out and starting switching everything.. So far only 1 problem, on the back of the block there are 2 senors on the old motor, the new motor only has 1. The old motors sensor on the left the bigger sensor thats what the new motor does not have a hole for what do I do? I took the sensor out and it seems to be a coolent temp sensor.. There isnt one on the thermostat area of the old motor.. so im guessing they switched them around in 92.. Someone help ive got the motor out already and its the only thing holding me back... what would happen if i drove without that sensor being used? **** what do I do..

 

common. someone knows what to do

 

Ok don't shoot me if I'm off ok as I'm sleepy

But the old motor has 2 sensors

1 is oil pressure and 1 has 2 prongs and that is the fan switch

If you look on the new motor that 2 prong sensor should be in the thermostat housing...you have to extend the wires from the old harness to reach the thermostat housing sensor

Thats whaf I had to do on my z6 in my 89 civic

ok let me know if that makes sense.

 

worked thanks alot... I knew it was somting to do with that new sensor being ont he thermo houseing...

 

cool

sorry but he isnt using the right option

the stock harness will not work in that specific pllug on the termosswitch located on the thermostat housing...

this is what u gotta do!
1- look behind ur 92-95 block... where u have that 2 prong sensor, the 5G motor has a plug... take the plug off...
2- go to ur 4G motor and take out that 2 prong sensor.... and then put it on ur 5G motor...
afterwards everything its self explanatory...

this is a normal step when putting a Z6 or any other OBD1motor into a 4G

I wasn't TOTALY WRONG

I just left out the plug part

but he figured it out...so I'm happy

edit: actually you are wrong I didn't pull my sensor out of my old motor I just used the one in the thermo in the 92 and part of a 92 harness so either way you do it and get it to work is right

 

there u go.... sorry i change the wrong term


but its actually more of a common sense to change the sensors from block to block other than tamperin and soldering and meesin with more of the harnes.s.... specially if u dont have that plug of that harness
yea ur way works.... but my way its more simple

 

haha you don't have to be a pro.....

this is funny because i'm helping out a newer h-tech member with the same thing your doing. IM him and maybe he can cut and paste our conversation we had about how to..... heres his post
