Jim,
This will help you. 1989 Dakota 3.9L MT used two controllers
4379.927 - Federal emissions standards (Non Calif.)
4379.885 - Calif. emissions standards.
Both are no longer available from Dodge direct BUT,
in regards to PN 4379.927 many dealerships show that they have them in
stock.
Try this number (Colorado Dealership) 1-800-426-6032
If your truck actually has PN 4379.885 try this dealership number
1-800-748-6118 (Calif. Dealership).
Any dealership can run a "parts locate" for you and we had pages of
dealerships
showing that they had 4379.927 in stock. Good luck and keep me
informed.
Frank
