Exhaust diverter solenoid

[floridamike1]

I'm looking for a source to purchase a new exhaust diverter solenoid. It is a 1999 Corsa 4 wire and I read that Corsa is only producing 3 wire replacements.
While searching the web I came across an OEM replacement at Central Coast Parts. Has anyone had any experience with them or this product replacement?
Any thoughts would be welcomed.

I wish you well on your search.
FWIW, I have a complete Corsa setup w/a 4-wire solenoid that worked the
last time I tried it.
It ended up being a piece I bought for the TR restoration but wouldn't fit
in w/the exhaust risers I used.

I have two complete Corsa setups if you are interested.

Performed a pull and hold test on my solenoid the correct way this time and determined that the solenoid was good. It turned out to be corrosion in the connector plug. Fixed it and now it works fine.
Thanks George and 22 classic for the info. Those solenoids may come in handy at another time if available.

I located this on EBay... hopefully it helps for future reference.

Late response, but the solenoids are super simple and rarely fail. It's just a metal rod and spring, inside a magnet that's activated by applying power. It's usually corrosion, as you found out. They also corrode inside. Easy to take apart and sand the rode and magnet to fix.
