Thanks for your help. I actually didn't have the wiring diagram for my car. This will help me with several upcoming repairs.

Well I cross referenced the oil sending unit with the one from AC delco that advanced auto is selling. They look identical to the one I have now. I think I'm good as far as the sending unit now. I really just need to know what wire connects to the sending unit though. Can I test the wires...

This thread has been dead for a while, but I just got around to working on my car. I posted another thread about my oil sending unit exploding. They gave me the wrong one. Anyway, back to this thread. The wire I found that looked brown/tan was due to oil on it. When I trace it back to the...

Well after looking online and contacting autozone, I found that they gave me the wrong oil sending unit. I was supposed to have a ps133 and they gave me a much smaller ps24. lol. They "couldn't find it in their computer" so the lifetime warranty didn't mean too much. I was stuck buying a new...

I replaced my oil gauge today and my oil sending unit. Someone had switched it out for an after market gauge and I want to put it back to stock. I have the gauge hooked up and tightend down the oil sending unit. I was told I was supposed to hook an orange wire to it. The wire is extremely...

Does anybody know if an oil pressure gauge out of a 76 will fit in a 74? I've searched google and get mixed answers. :upthumbs Thanks

I'm actually very interested. I need a few gauges. My tach doesn't work, my oil pressure gauge, amp gauge and clock. How much would you be asking for each or all of the parts?

yep. It has an automatic 350 turbo in it.

Hi all, I've switched my old points distributor over to an HEI in my 74. However, it no longer has the mechanical device to run the rpm gauge. I was wondering if a gauge out of a 75-82 would work in a 74. I know they switched over to electronic in 75. Thanks

I've also ran a wire directly from my battery to the HEI distributor. Not sure why the previous owner did it this way. He connected it to a toggle switch. You said it looks at the voltage at the horn relay. Where is that located. My gauge is setting to the far left indicating no charge...

I have a friend that is selling a 700r2 with a shift kit out of a 1980 trans-am. I was wondering how hard it is to put this into a 1974 corvette with the v8 (original L82 has been swapped for an unknown v8). I've been told that I will need custom mounts and a TV cable. I'm not really sure...

Is the 200r4 a direct replacement for the turbo 350/400? I'm almost positive when I was doing an oil change my tranny was labeled hydromatic turbo 350. While I need to cut down driveshafts and get new mounts for a 200r4? I'd like to keep it somewhat close to original in case for some odd...

I don't have an expansion tank on my car. I've got a hose rubber hose that comes out of the radiator right by the cap. Should there be an expansion tank on a '74? I know 100% it is coming out of that hose. I've seen it coming out. There is no space in there to fit an overflow tank. Also, I...

On my drivers side door the windows seems to be sliding off track. I can roll it about half way up, and then I have to grab the window and slide it towards the back of the car before I can roll it up the rest of the way. It is also really wobbly. I'm assuming that's because I'm missing the...

I've had a something strange happen to me the past two days. I don't recall it ever happening before. I drove to work and when I park in the parking lot coolant is coming out of my overflow and running out the bottom of the engine bay. The rest of the engine is dry so I am certain it's coming...

Ok thanks a lot for your help. I would say it's safe to assume the tan wire I found is the correct one. It definitely looks original and has 12v. :thumb

I pulled the gauge bezel off yesterday and it appears the wires coming off the oil pressure gauge are blue and pink. However, there are several gauges with blue and pink wires. To make it even worse, I don't see a single blue or pink wire under the hood. Do they change color somewhere in the...

The previous owner of my corvette replaced the oil gauge with some cheezy sunpro oil pressure gauge. I bought a new sending unit, but don't know which wire to connect to it. He swapped the motor out and there is a couple wires he never reattached. Does anyone know the color of the wire? I...

So I'm trying to figure out how you got this info. I understand part of it. digits 1) is the make of the car. In this case chevy 2) Is the last digit of the year. Not sure how you knew it was from the 70's 3) City engine was built in 4-9) is the production number What information did the...

Thanks a lot. Does anybody know how durable the block is on these motors? I have edelbrock preformer heads, mild aftermarket cam, and 4 barrel edelbrock performer carb. I don't know if I should go ahead and build this engine or buy something better. I want to turn it into a 383. I'm...
