Adding factory cruise to base model 91 Sierra

[midwest]

I have just recently purchased a 91 GMC Sierra K1500 Base model truck. It is in unbelieveable condition and has the 4.3 5 speed drivetrain. I got it due to gas prices going up and my 01 3500 dually is killing me. Anyway, I need to add factory cruise control to this truck. I had done it on my 01, all I had to do was the new multifunction switch and I was ready to go. I believe it will be a bit more difficult on this one, So far I'm thinking,

 

New control switch on colum,

cruise control module

cruise control cable

 

Has anyone done this? Am I missing anything?

 

Thanks for any help you could offer!!!!!

 

P.s. Love the site...
