If your truck is a 96-00 vortec truck then your PCM will be able to control the injectors with the correct injector constant the tune. You'll need to get pigtails for the injectors and splice into the stock wiring. You'll also be able to retain all of the stock sensors except for the EGR with...

Information about buying one can be found in this thread. Technically it is not legal but can be made to look very similar to stock and function just like stock. EGR will have to be added...
I might have a solution for you. If you have the same DRL relay as me (part# 12077866), bend pin 87 as pictured below and re-insert the relay. On my brother's 96 tahoe (because my DRL don't work anymore, they have a mind of their own) when I did this, the DRL don't work anymore (DRL fuse still...
I have that schematic too but it doesn't make any sense the way they have it.
What part number do you have for the DRL relay? Mine is 12077866 and it also says OMRON and 7866 on it.
I believe the finned thing you disconnected was the DRL Diode but by disconnecting that thing it should have done the job.
This schematic is for "without" the option Luxury (Denali/Escalade). I have a different one for luxury in my book which has a different orientation for the DRL...
Mine stopped working randomly 4 or so years ago. But then a couple of months ago out of the blue they started working again so I just yanked the DRL/FOG fuse.
I'll see if I can find a schematic in the service manuals I have to try to disable them without taking out the fogs.
I tried doing what you did and my steering is back to what I remember it being like. No more tighter feel and wanting to return back to straight. Driving takes no effort at all now.
Here is some info about adding a cooler if you do decide it necessary later. There was also a nice discussion about adding a cooler on Hydratech's forum before they did away with it.

That was you(joemama422) on pacificp that was talking about it. I'm 99bluetahoe over there.

Here are the directions on how to change it:

There have been talks on another forum about the sensor needing to be clocked to a certain position (zero) for it to work correctly but I've always just thrown it on. I'm going to test clocking it...
