Yep, 88 k cars (T&C, 600E, New Yorker, Lebaron) have the same bulkhead as the older stuff. I took an 88 New Yorker Turbo harness and plugged it right into my 87 New Yorker Turbo to convert it to smec. Pinouts on both are the same so it's plug and play.
Johnny I thought Eric over on the PNW-SDAC list said he had one from a 600E??
