Howell Engineering LT4 harness not working Hi guys. Got an issue with a harness I purchased form my LT4 swap.
I called howell engineering and told them what I was building. LT4/4l80e swap into a 56' pickup.
The guy there said no problem, we'll build you a harness and ecu for your application. You'll just need to get a stand alone TCM.
Fast forward to this month. We got everything installed and the engine has about 25% power. Got a tuner involved and he logged into the ECU and said it's in limp mode and it looks like it's due to no VSS sensor signal.
Call Howell and they say " gee..yeah, not really sure what's happening as we've never built one for a SC application". So now i'm paying a couple guys to try and do their R/D to find a work around. Needless to say i'm pissed, I would have never bought this crap if I had known I was the guinea pig.
Anyone ever run across this issue doing this swap. Did you find a VSS work around or figure out how to properly pin in an old 2 wire VSS instead of a 3 wire?
Thanks for any help

I looked at the Howell website and it clearly states they have an LT4 harness, which implies it is for SC.
And then they don't?
Write, but don't send yet, a letter to the FTC and the BBB and include them in your communication to Howell, stating you will mail them if they don't quickly refund your money.
