Well, I went and picked up a new 7805 from Radioshack, I'll have to wait until either tonight or New Years day before I get to desolder my LCD board to get to the 7805 to change it out... I'll post results when I'm done...

Thanks for the inputs.

Well, I guess I got anxious - so I went ahead and desoldered after work this morning - desoldering that LCD from the other board is a bit of a pain...

I got the 7805 off - ohm checked it again to verify my results and they were the same - I ohmed checked the new 7805 and some of the measurements were identical - so I was concerned... But there were 2 measurements that were not the same, so I figured I'd try it anyway..

Soldered everything back together (also touched up 2 questionable solder joints)- hooked it up to PC power again to make sure I didn't really screw anything up and it still worked like before

So, the real test was plugging it into the car (I had left my temp power and ground cable soldered in). So, after waiting a few mins between power off and on - I plugged it in.

And the LCD came on - and the Ver. came up and it worked!

So - the easy part is done.

Now all I have to do is hook up the VSS and the INJ, and make my power and Ground a more permanent set up. I should hopefully have it done by the end of the week. Thanks again for the inputs.

Cables installed and routed and concealed.

I made an enclosure out of an Old Spice Deoderant stick (the semi clear one) thanks to some ideas I saw on another thread

I tested it out today (20 miles).

I used the settings dcb put up for his 97 Saturn info -

It seemed to work really well with all the BIG displays, but it froze on me when I used the small displays... So a total of 2 freezes...

I'll read up on the freeze fix, my Guino has Ver .73 on it.
