No they don’t dim unfortunately. But the good thing is they only come on when something is wrong
Lol....fair enough. Keep up the good work. I've been debating a LS swap for a while. I love the low down TBI torque. How's the "get up and go?" I know you came from a 454, so not exactly the same as a 350. And no....I don't want this to turn into a LS vs TBI thread, just looking for your experience.

Since the old 7.4 was tired and burned gas without making any power I decided to swap it. I bought a donor truck last year, a 2002 Truck with 156,000km on it that was smashed and started collecting the parts I needed until I was ready to pull the trigger. I reworked the harness myself in my spare time, stripping what wasn’t needed and rerouting things for a little cleaner look. The truck was a dbc but I swapped it out for a dbw tb. I used a 94 diesel pedal. E fans are from the same 05 truck the tb, tac module, and ecu came from. Fast forward to a couple weeks ago when the alternator went on the 454 and I figured instead of wasting money on a new one, I pulled the engine and started the swap. I was surprised how everything pretty much went together without any real hiccups and it started on the first crank. Drove it around for about a week and a half and first gear in the th400 decided to say bye bye. Built 4l60e coming next. Didn’t take many pics but here are a few. The first pic is the tow haul button I installed for when the new tranny shows up the green led on the far right in the cluster lights up when tow haul activated

I have a 94 and did an LS3 swap. it works great, except I cant get my oil pressure gauge to work. When I crank the truck it pegs out. Any suggestions would be appreciated!

Does it only peg out while cranking? What does it do after it starts? I'm assuming you reused the 94 sending unit and put it on the new engine?
