Did anybody ever change the weatherpack plug to the MAP sensor? Mine is missing the little clip that holds it to the sensor, and to top it off, the plug has a crack in it. It seems that the whole plug has very intricate wires, certainly hard to splice. What are my options, Injuneer, Shoebox, anybody.

 

Just get the pigtail part # from Shoebox's parts # listing page.

I replaced just the green connector housing with clip last summer without splicing a new pigtail. I scored a couple map sensors with unbroken clips at the local junk yard, numerous gm cars use the same green connector so they were easy to find. Make sure to write down the color of wire to the appropriate spot on the connector, unhook the back flap, pick out the 3 purple insulators at the back of the connector with a needle or jewelry screwdriver. From the front push the metal bayonet terminals out the back of the connector with a 3/32 nail set towards the wires. The terminals have barbs which keep them in place so it takes some force to push them out. Remove the broken connector on the car and just push in the terminals on the new connector. I probably didn't explain this too good but it is easy to swap connectors and you could practice on some old ones from a junk yard first. It keeps you from cutting and splicing existing wires.

 

Kevin, don't the junkyards pull the engines and try to sell them, if I'm not mistaken they sell the engine complete, that means with the sensor still attached to the intake.

 

The problem is that the MAP harness connectors in particular seem to get brittle from the heat and crack. Using a junk yard piece would seem to be a crap shoot.

 

Maybe I should call them salvage yards. The one I go to all the time is open to walk around and remove the parts you need and pay little or nothing at the office when you leave. The larger parts they will remove for you if you want, its great for finding various hard to find hardware and trim pieces. The engines they want to sell they pull and leave the wrecked cars to be used for parts, most have already been canniballized!
The tab on my map sensor was broke ever since I got my car and it never fell out, I just replaced it because it looked tacky. The connector I took off a wrecked car looked as good as new and was free, I wouldn't think of putting a brittle junk piece back on. Like Fred said, buy a new pigtail or swap a new or used connector housing on like I did. The part number for the housing is #12015793 for about $1.50. The pigtail number is #12085502 for about $15 and most people would solder & shrinkwrap it.

 

Thank You gentlemen.
