    Added A/C to R1500 need ecm pinouts

    I just added A/C to my 1955 chevy pickup. I forgot no fan in 1990. Need pinout for A/C clutch to ECM. Have low idle problem. This a R/V1500. Not CK1500 Same ECM but uses different pinouts than CK1500. There are different wiring diagrams. While moving lost warring diagram.
