Identify These Plugs

[Gearhead4G63]

Ok this is a 4G64 Harness what are these plugs for? Can't seem to find there mates.

The first (white connector) is for the fuel pump relay module.

Second one looks like it is related to the front O2 sensor. Here's a few possibilities, with which you can compare the wire colors to determine what it is.

A-94: Front O2 Sensor
1 - Red
2 - Black w/ White stripe
3 - Yellow
4 - White

A-103: ELC 4-Speed Auto Transaxle Control Solenoid Valve
1 - Blue w/ Yellow stripe
2 - Red
3 - Gray
4 - Orange

A-112: Heated O2 Sensor Wiring Harness and Control Wiring Harness Combination -- this connects A-94 to the rest of the harness, a kind of intermediate connector
1 - Black w/ White stripe
2 - Red
3 - White
4 - Black

Ok now I know why I'm not getting fuel, and it's A-94 thanks man, now with all that being said I dropped my 64 into a gst the only thing I have changed is the engine harness, I have already re wired the connecting plug by the fuse box, I color matched, could I have done something wrong? I'm not getting a starter signal, nor do my windows or sunroof work, blower, possibly not even getting spark, could my Ecu not be getting power?

Also will I have to rewire the 64 fuel pump module plug or did I just miss the gst harness mate for it?

The starter circuit is independent of anything else you've mentioned and is identical on the 63 and 64 systems. Unless one was an auto and the other a manual, there shouldn't be any problems. Check your connections at the starter, at the battery, and your fuses.

As for the fuel pump module, I assume you're asking because you no longer have the unit from the Spyder? It would be part number MR239764. What appears would work to me may not be suitable advice, so I'll send your here for reference on how to jumper the connector to run without the fuel pump module for testing purposes: http://www.justanswer.com/mitsubishi/7vv7a-mitsubishi-eclipse-spyder-gs-99-eclipse-spyder-2-4.html

Ok have the module. That problem solved, I'm getting 12.5 to my starter signal fuse, I've seen this problem before "might not be mine" but could the aftermarket alarm on the car be stopping my signal?

Could be. Aftermarket alarm systems can be a real PITA.
