Message	Here is pinout info for the different years. The ECU harness is very easy to get to, will tell you which injector to go to first (no fun pulling injector connectors) and can help quickly identify a possible bad harness connection to the injector. Disconnect the battery first. Disconnect the ECU harness. Continuity should be between 10 and 14 ohms. Year 90-94 Injector 1 - ECU Pin 101 to ECU pin 58. Injector 2 - ECU Pin 110 to ECU pin 58. Injector 3 - ECU Pin 103 to ECU pin 58. Injector 4 - ECU Pin 112 to ECU pin 58. Injector 5 - ECU Pin 105 to ECU pin 58. Injector 6 - ECU Pin 114 to ECU pin 58. Year 95-96 Injector 1 - ECU Pin 101 to ECU pin 45. Injector 2 - ECU Pin 110 to ECU pin 45. Injector 3 - ECU Pin 103 to ECU pin 45. Injector 4 - ECU Pin 112 to ECU pin 45. Injector 5 - ECU Pin 105 to ECU pin 45. Injector 6 - ECU Pin 114 to ECU pin 45. Here's a link to the pinout of the ECU harness connector as viewed from the harness side of the connector.

Follow Ups	Injector Ohm Testing - J-Mart 00:06:13 02/14/08 yes - method #1 works fine, no idea about the rest. (n/m) - Bernie (NoVA) 00:08:27 02/14/08 Thanks Bernie. - J-Mart 00:15:22 02/14/08 why are you connecting a "loose injector" to the EFI? (n/m) - robo (sebring1970) 02:21:21 02/14/08 Should read loose injector connector. - J-Mart 10:01:47 02/14/08 You can also do it even easier at the ECU plug. That - Audioquest 07:51:48 02/14/08 Why not just ohm the injector itself? - Woody75 (Denver) 08:57:09 02/14/08 Depending on the multimeter or injector location - J-Mart 10:00:16 02/14/08 Really? Takes me about 1/2 hr to do them all at the injector - Audioquest 10:17:49 02/14/08 Even so I've still been able to do it. (n/m) - Woody75 (Denver) 10:28:15 02/14/08 It's a lot easier withthe throttle cover off. (n/m) - BlackholeZ 15:38:59 02/14/08 As Audioquest said, do it at the ECU harness first. - DVDBURN (MD) 23:28:42 02/14/08
