toastemcutlass Posted May 24, 2004 Report Share Posted May 24, 2004 so im going to be doing the l67 swap this summer and im going to sell my 3.4 soon...but the only problem is that i need the 3.4 harness to wire into the new harness, so my question is, are 3.1 harnesses the same...the reason i ask is because the computer will go with the 3.4 and wasnt sure if a person swaping it from a 3.1 could use it, with there harness?

sl3196 Posted May 24, 2004 Report Share Posted May 24, 2004 You have to use the harness from the l67 in your car. Also you need the fuse box's, pcm, and so on.... I think the harness is engine specific. Quote Link to comment Share on other sites More sharing options...
