No, plugs are different

 

I wonder if I could snip the LS1 plugs and resolder the 11+ plugs and reuse my Nelson's LS1 relay harness?

 

Yes u can, the relays may need to be changed as the truck fans pull more current.

I'm going to posting my two blackbear fan harness in the classified section soon.

 

pm price

 

Got a harness from TXSZ66Avalanche hookep me up witha bad *** harness. He origially sold me a bb harness and it got lost in the mail. This is a top notch quality harness. Should pm him for the harness maybe he can hook you up with on. Here are some pics of it.
