joshuadreed Posted January 28, 2009 Share Posted January 28, 2009 So I was installing a new manifold gasket and decided to install new seals and electrical connectors also. When I was taking it apart I was kinda dumb and cut the injector connectors thinking "oh well I'm just gonna put new connectors on anyways". Now I'm looking at the wires and they're both black. Does it matter which way the two wires are installed into the connectors??? If so how do I figure out which is which... Thanks for your help.

naviathan Posted January 28, 2009 Share Posted January 28, 2009 Seperate the wires and turn the ignition on. You should get a good 12V on one wire measured against ground (or batt. neg.) Although on the stock injectors it might not matter, you also might not want to take the risk. If you ever plan on upgrading to decent injectors you'll want the polarity right.

jeffer949 Posted January 28, 2009 Share Posted January 28, 2009 Im not saying your wrong but ive never seen an injector that needs the polarity right. If you could give me an example that would be great. When i redid mine on my stock harness I didnt worry about it and it worked fine.

MJLamberson Posted January 28, 2009 Share Posted January 28, 2009 Yeah, it doesnt matter which wire goes where. Quote Link to comment Share on other sites More sharing options...
joshuadreed Posted January 28, 2009 Author Share Posted January 28, 2009 Awesome! It looks like the general consensus is that the polarity doesn't matter. I kind of figured as much because if it did matter the factory would have likely used coded wires. Thanks for your replies. Quote Link to comment Share on other sites More sharing options...
