anyone have wiring diagram for 91 Cheyenne?

Spend the $8.99 on an adapter at Autozone and you won't have to cut or splice anything.

and while you're at it, toss the old radio head and tuner too... then go to the dealer and get the radio delete pocket.. its a great little cubby hole. I paid around 15 bucks for mine.

I went with (2) 2 1/4 digital gauges in that spot; vacuum and ambient air temp. The Actron/Sunpro dual gauge cluster fits just about perfectly.

Doc

All great ideas, thanks a bunch!! Probably saved me alot of reaching in and out of the dashboard hangin upside down on the stearing wheel....

Ooers... a vac gauge.... I've got a dual pod on the A pillar, Autometer Trans temp and a SunPro mech. Oil pressure.. I'm toying with getting the triple gauge full A pillar and adding a vac gauge, never can have too much information... I'm still stomping on it to watch the OP fly past 50PSI (sooooo much better than the 25psi max hi had before).

I really like the vac guage. I went with the Cyberdyne digital gauges and LOVE em.' Kinda pricey for the vac gauge ($70 IIRC) but well worth it.

Nuthin' like tons of oil pressure with a linear increase with RPM eh? Ol' Elky sits right at 25psi, ANY RPM, he he he he he.
