Does anyone have the pinouts for the non power steering column and the ISIS system?
I think we need to rally for a working search function. All of these same questions will keep getting asked for years to come without it.
I'm not sure what you mean about the non-power column. There is the race column, which is just a rod, really. The two street columns that were shipped in the SLC are both power-assisted. The XLR has power tile and tele; the Olds column has power tele but not tilt (or is that backward? In any case, one of the functions is power-assisted, the other is manual.)
The original Cadillac XLR column is well documented. The newer column is from (I think) an Olds Aurora. I haven't seen anyone take this apart, but in either case, the provided harness should just connect up to the column in your car.
I've found that most wiring diagrams are available on the web. Here's a link that has the XLR column, as well as the Olds column diagrams: Search Wiring Diagrams

I find using Google search can be used when the site search will not work. Add the search term: site:GT40s.com after your search input. I used it like this and got 13 results from the forum:
