[urq] old MAC-02 vs newer MAC-02 for WX prior post of Alex Stickler and R Houk

[steven j]

I picked up the newer 035 905 393F  MAC-02.   There are some posts that say this 'F' works in the older cars and others - maybe not.

Also - with a used CPU is are there any pins whose resistance I should check to make sure the unit won't fry something if it's a defective unit?

I flipped through ETKA and did find the ECU.   Is it there?
