Question
I have 92 blazer k1500 and had cassette w/o EQ I just got 1 from a 90 pickup and it plugs in and and works but there is an extra plug on the e/q one and my truck does not have the extra plug for it. and it has 2 wires inside yellow and white,what is power for these wires.

Answer
Don't know but you can go to these two web pages below and figure it out for sure:

http://www.modifiedlife.com/1992-chevrolet-s10-blazer-car-stereo-radio-wiring-di...

http://www.installdr.com/InstallDocs/GM/Suburban.html

(Above is for different year but I think the schema is the same)

And if you go to the modifiedlife page above on the right hand side of the page you can find the wiring guide lists for the 90 pikup.

From these I hope you can figure it out!

Best wishes.
