Damn red rocket

Mine is an LS1fans.com harness, bought it about 1 1/2 years ago. It first burned out 2 relays, then next time melted the relay block itself and the fuse holders too. Left me stranded in 105 degree temps because the engine overheated. I rebuilt it using 80 amp relays, mega fuse holders, bigger wire, etc but I still don't trust it so I ordered an OEM harness from @ScottyBoy. I no longer recommend anybody's aftermarket harness, there seems to be something missing in their design. I have no idea about Nelson's harness but they have a reputation for melting and I haven't heard anything about them fixing the design.

Keep us posted about this. Maybe even start a separate thread. This will be VERY useful information for anyone who has to replace their ignition key cylinder.

I may have to start my own thread, this has been a nightmare. I have a guy coming out tonight with a Tech2, hopefully he can figure out why it does not let me go into the relearn mode. I am still on the OEM BCM, have the replacement one just in case thats the issue. I want the guy to take a look at the BCM for codes and see if he can get into the PCM and take out the need for VATS/Passlock communication so the truck doesn't cut off fuel to injectors. He has said that he's worked on trucks where owners replaced BCM, PCM, harness, ignition cylinder, and housing and truck still wouldt stay on. I am at a loss if this happens.

Your best bet is to get an OEM harness, the aftermarket ones have the issues with the relays, the OEM ones mount behind the under hood fuse box away from the heat for the most part the aftermarket ones mount a lot closer to the engine, if the wiring was longer you wouldn't have that issue, I've heard some that say the aftermarket wiring isn't as good as the OEM setup, here's the OEM harness I'll be using after I get the fans turned on in the PCM

Thanks for the input. That was my first choice but most yards around me won't let you pick n pull and eBay was about $30 more. I may just end up reworking the Nelson harness to wire tuck it and keep the relays away from the heat.

Out of curiosity, how long did it take you to pull the parts off?

maybe 30 minutes.
remove rubber boot on outside of arm. pull the arm off. pop the big plastic interior surround off, then the lower half plastic with the strap has a screw in it. (was easier to pull it off once you pop the window release to get the plastic off)
unbolt the wiper motor and black plastic rest for the arm. zip tied the plug and the tube so it doesnt rattle. then button it all back up. done deal

No problem, if the Nelson one doesn't work there's a member on here that sells the OEM ones that's where I got mine from
