I remeber (Brad?) someone memtioning that a good replacement for 90's Imp air suspension compressors are used units from 80's Cadillacs. Well I picked one up for $10. But I can't figure out how the thing hooks up- has 4 wires (ground, +12volts, and???), and 3 hose hookups.... This any similar to the Imperial's OEM compressor? How does the OEM one wire and hook up? __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com
