Wiring issues continued... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an 88' k5 blazer that is HOPEFULLY in the final stages of wiring. The vehicle starts and runs fine. MY gauges do not work for the oil pressure and the water temp. I found the wires for both to hook up. Here is the problem...the oil pressure switch...i cant find where to screw it into the block. The hole where the oil pressure sender for the computer is correctly in its place behind the Dist. and i cant find a hole for the switch. Can anyone help me? I also need to add that this project is an 88' body on an 82 frame and drivetrain...with a 79' block converted for TBI. Does that mean that there is not an extra hole for both the sending unit AND the switch? Thanks alot for ANY help!!!

Look on the driver’s side of the engine block above where the oil filter is. That is where the early TBI trucks had an oil sender for the gauge.

Here is a link to a post with some photos. Photos that had been up-side down have been edited to make them right-side up.
