LS1 & LS6 PCM (ECU) Pinout

Don't say we don't do anything for you guys! 

We know how frustrating it can be trawling the web for info, only to find a forum post from 2008 with a broken photobucket link. So here is a condensed copy of the LS1 P01 and P59 PCM pinout for 99-06 AUSTRALIAN delivered vehicles for your convenience.

We understand the DIY'ers at home sometimes want to have a go at building their own swap or standalone harness and we have absolutely no issue with that, as long as it is done with safety in mind. Safety comes from knowledge.

So use at your discretion, understanding we are not liable for any misinterpretation of this information and LS Swap the world! 

Please Note - All PCM's Will Require VATS to be Disabled before they can be used in a swap application. We offer this service and it can be found HERE
