Guest Zya1964 Posted January 2, 2005 Share Posted January 2, 2005 Is the plug 2 on the harness the one that plugs into the ecu or did I not get something. Thanks, Neal Quote Link to comment Share on other sites More sharing options...
GrayZee Posted January 2, 2005 Share Posted January 2, 2005 I don't really know how to answer that as I'm not really sure which "swap" you are talking about.. However I assume you are talking about a L28 turbo The wires are as follows: Plug 1= BR 12v power source. Positive G 12v power source. Positive Plug 2=Y start signal (+) GL ground for inhibitor switch YW speed sensor (not necessary) Y A/C signal (+) YW coil (-) (must use ignitor) B fuel pump ground if using modulator Plug 3=LR fuel pump relay G ignition .signal (+) for air regulator W not used Y not used BW ignition signal (+) There are 3 plugs on the ecu but those are not the ones being referred to.. if you were to lay the harness is out accordingly around the engine and through the firewall the #2 plug would be near the ecu plugs but a little further up the harness (between the ecu plugs and the firewall grommet) Plug # 1 and #3 would both be near the battery cross reference them with the color codes and you will know for sure.

Guest Zya1964 Posted January 2, 2005 Share Posted January 2, 2005 yea sorry 81 l28t i'm just making sure the number 2 plug is the one that goes directly into the ecu and not some other part of the harness i didn't pull. thanks again, neal Quote Link to comment Share on other sites More sharing options...
