Buying Connectors?
The end of the connector for my TPS is partially cracked...It's got 4 prongs, each on surrounded by a plastic tube like thing. One of these tubes is cracked and is exposing the prong. The connector still fits into the TPS and the car still runs beauty, but I would like to replace it. Can I buy just the TPS connector? I'm hoping I don't have to buy a whole wiring harness.

The connector is servicable. Chances are you can replace the broken piece without even cutting the wiring. Parts are available from the dealerships for next to nothing. The hard part is finding out what part numbers to use. If you have a shop manual you can find out what kind of connector it is and if you have a parts guy who has a lot of tolerance he should be able to get you the right part.
Otherwise you can buy the plug with pigtails at most auto parts stores, but then you'd be looking at spending a lot more money and you'd still have to either disassemble the connector and rebuild it or cut the harness and wire in the new plug.

Ok cool, thanks. I'll go into the dealer tommorrow and talk to them. I don't mind soldering on a whole new connector if that's what it takes...that's no biggie.

There is no soldering to it just get you the tool from pep-boys that releases the pins and put them into the new housing.
The bad part is I have not found a dealer that sells the connector componenets. The only place I have found that sells the pieces is in cali. and you have to have a $25 minimum order.

I forgot about the connector with pigtails, If you can find that just use the housing. It is real easy to get the pins out if you have the right tool. and those things are cheap at pep-boys

This is the tool. You will need to use the one that is straight across from the screwdriver blade, it fits around the terminal and is spring loaded to eject the terminal from the housing.

Ok you got me on the MAF. I am building a SD harness and have not messed with a MAF connector.

I swore it had four but now you got me second guessing myself...Unfortunately I don't have the car stored here to check. But I will be the first to admit I may very well be wrong.
Matthew, you got mail.

The 4 prong adapter is your IAC motor. It is directly below the TPS sensor, and is in a "square" pattern.
Bowman Distribution carries weatherpack connector shells. The part number you want for the IAC is 7357-1. If it really is the TPS you need, then that is part number 7352-1.
Their number is 1-800-927-3555

No it is the TPS...I know which one it the IAC. There's no mistaking the two. It has been confirmed it's three...guess my short term memory is not as reliable as I thought!
Thanks for the number. I'll check it out.

Comments and questions..
Question for Long&Low: what is the place in california you found that sells just the connector housings? Or perhaps connectors with terminals that i can crimp on to existing wiring?
Comments.. I had to change a few of my connectors (MAP, both ignition coil connectors, O2, fan temp switch). I found everything but the fan temp switch, although the coil connectors were something like $17 each! ouch. The tool they had for taking the pins out of the connectors was also different than the pictured tool above - the tool my pep boys had looked like a long, skinny screwdriver, only it had a hollow tip for going aroudn the connectors. took a LOT of pressure but eventually the pins would come out.
Further comments... my two coil connectors (the factory GM ones) do not have removable pins (BOOOOO GM!) so only choice is to splice the new connector into the old harness. Further, the pep-boys connectors had shorter terminals inside of them. I used them anyways, they seem to work, but....the terminals inside of them seem awful short. I will probably swap them out with factory GM connectors if I can find good ones.
So in summation. MAP sensor was a pain, but doable, and good results. Ignition connectors have to be spliced, connectors are a bit questionable. haven't done the O2 yet, and they didn't have the fan switch.
