| - | ====== GM 3 or 3.3 Bar Installation Example ====== | ||
| - | Parts needed: | ||
| - | - GM 3 bar map sensor from www.gmpartsdirect.com. Part number 16040749 $59 shipped | ||
| - | - map sensor harness off of a camarobird (or other GM car) in a junkyard: $0-1 | ||
| - | - OR you can get it from NAPA P/N 784524 - GM Weather Pack Triple Male w/seal Housing. | ||
| - | |||
| - | You will also need male pins for this connector, since it is just an empty shell. ~$4 for all | ||
| - | |||
| - | - OR You can get the connector pre-assembled from GM, the part number is 15305891. $17.26 + shipping | ||
| - | |||
| - | 3) Vacuum hose (one foot will be plenty) | ||
| - | |||
| - | 4) T connector to splice into the intake manifold boost/vacuum source | ||
| - | |||
| - | |||
| - | |||
| - | Tools needed: | ||
| - | |||
| - | Xacto knife/razor blade, and some vampire connections (or a soldering iron if you plan to solder your connections), and of course some zip ties. | ||
| - | |||
| - | |||
| - | |||
| - | This VFAQ will assume you have the junkyard MAP connector harness, or you have already assembled your store bought connector | ||
| - | |||
| - | |||
| - | |||
| - | Now I assume you know how to find the MDP sensor. It is the sensor | ||
| - | |||
| - | that sits on top of the intake manifold of a 2G. Unplug it, but leave it | ||
| - | |||
| - | in the intake manifold. | ||
| - | |||
| - | |||
| - | |||
| - | |||
| - | |||
| - | Try to insert the empty Weather Pack connector into the MAP sensor. | ||
| - | |||
| - | It won't go! See those little tabs inside the MAP sensor holes? Well, | ||
| - | |||
| - | you have to make slits with a razor in the connector you bought to | ||
| - | |||
| - | match. Here is what it looks like before: | ||
| - | |||
| - | |||
| - | |||
| - | |||
| - | |||
| - | And here it is after the cut: | ||
| - | |||
| - | |||
| - | |||
| - | Here are the connections: | ||
| - | |||
| - | MAP Function MDP | ||
| - | |||
| - | A Ground Black | ||
| - | |||
| - | B Signal Light Green-Black stripe | ||
| - | |||
| - | C +5 Volts Green-Yellow stripe | ||
| - | |||
| - | |||
| - | |||
| - | If you want to solder, that is best, but I just used vampire taps. Tap the connector into the appropriate lines. | ||
| - | |||
| - | |||
| - | |||
| - | That's about it. Hook up the vac lines. Use a zip tie around each connection. | ||
| - | |||
| - | Tape up your wires with electrical tape, and secure your map sensor somewhere safe. | ||
