I'm new to chevy world,have always been a ford guy and all my friends are chevy guys,
Got the car this past winter and friend said it was messed up but took it any how and you guys on this site really helped me < boy that opti was a pain , but not hard. Thanks!!

Now I'm trying to put in some gauges but not to sure where they go???help!!
These are the gauges I'm trying to hook up.
elect water temp, Mec oil pressure , air fuel gauge , trans temp , tach .
If any one knows were to hook them up , or has any pics that would help me.
Thanks guys

 

elect water temp: There is a plugged hole in the passenger side head, between #6/#8 that can be used for the sensor. Tight fit though. Its a mirror image of the one on the drivers side where the factory coolant temp (gauge) sensor is located

Mec oil pressure: There a plugged hole in the block right above the oil filter. Shoebox has a picture on his Tech Pages. I have a mechanical oil pressure gauge connected there.

air fuel gauge: First question is "why"? It not going to provide much more than a psychedelic light show. You need to splice into the purple wire between pin C8 of the PCM and the harness connector at the passenger side, or the purple/white whire between C20 and the drivers side.

trans temp: There's a plugged hole on the passenger side of the tranny case. Shoebox may have a pic of the location.

tach: White wire from pin A13 of the PCM is the output signal for the stock tach.

 

thanks!! on the air fuel gauge it was taken out of the mustang i had.
1 more thing I have a jet fan switch that I have yet to put in and it also says use the spot in the pass side for that now what should I do for the gauge.

 

pin 13??? This my sound dumb but were is pin 13 and how do you use it??
Sorry like I said I'm new to this

 

Shoebox has the complete wiring diagrams for the 95's along with the PCM connector pin-outs:

Why use a JET fan switch? Why not get the PCM tuned for the tempertures you want? Or simply add a manual switch so you can turn the fans on whenever you want (also diagrams on Shoebox's pages). If you need yet another coolant temp sensor, I can show you how to splice it into the coolant return line from the back of the heads..... that's where I put an extra sensor.

 

Do you have pics on what you did??
The fan switch and a few other items were on my xmas list that I got.and thats why I have them. I'm learning more and more every day

 

Question on that one.. is the fitting you mentioned by the filter that you used 1/4" NPT? Looking at buying an autometer 3321 gauge today and I wanted to make sure it would work with what it has!

Also, did you put it in a gauge pod? Any issues with oil leaks on the back of those? My friend had an autoparts store (sunpro) cheaper gauge and had issues with it leaking.
