ls swap is RUNNING. a few quesions...

[bohmankid]

I started my 5.3 for the first time on Saturday 03-09-13. It sounds great. Started right up and sounds healthy. I drove it around my neighborhood and MAN-O-MAN the power and throttle response is awesome
Now i have a few questions. I did a little research but want to put this post up to double check.
I need to monitor my temperature. Is there a way to use my sensor off my old 350? will autometer #2277 allow me to use my 350 sensor on the pass side head port? OR will autometer #2259 allow me to use my stock gage?

Also, how much luck have any of you had hooking your electric fan relay up to your computer? I have a relay with an on/off sensor mounted to my radiator, but using my computer would be cool.

Things I still need to do:
VSS: thinkin about using the SEN-01-4160
steam line: I purchased the T fitting from JTR
OBDII port: I'll just wire it up how lt1swap suggests
check engine light

anything I'm missing? Thanks for all the help with getting my truck running, I did everything myself. I'm a 21 year old, never taken any automotive class, learned everything I know from trial and error. I couldn't have done it without this website.
