If what I've found is accurate, the speedometer itself takes the VSS AC signal and converts it to a DC output that is then sent to 3 other components. The receiving components are ECCS (ECU), Power Steering and Cruise Control. So the ECU itself does not tell the Power Steering Control Unit to adjust the amount of assist.
At the moment I am attempting to confirm what type of output the speedometer is sending. Some search results state its a frequency output of 2Hz - 120Hz, others listed it as a PWM ranging from 0v to 5v, and all of them agree its DC.
I'm still digging through related posts on the forum here as well, though a lot of links on older posts are dead.

Im going to be welding up and respraying the rear hatch. Id like to replace the glass trim at the same time and ill use a universal trim.
Question is do i have to remove the glass and if so how do i do it without smashing it. its a swb so replacement glass will be a pain to get hold off.
i think i will get a much better respray result with the glass out as i hate that nasty look of not bothering to remove trim when spraying.
Anyone help?
