does anyone make a harness conversion ?
The kits in the link are full aftermarket control. Good for swappers that start with nothing and have no chassis support and dont want to deal with tuning the stock PCM
LS1 into a LT1 car is about the same as a V6 to LS1 conversion. Same chassis, OEM engine. Strait forward
Your LT1 gauges are all analog, so make sure the new engine has analog senders and it will still work like stock
