Mercury 2 Box with Altitude sensor.
Bought it for my Patrol with the TB45E engine and the car did not run well with that ECU. Found out on the Patrol Forums that the Nissan Patrol 4.5 runs the best with its Stock ECU so had that put in again.
Nothing wrong with this box just selling cuz its pointless, i ran the car with this box from Richards bay where i had it installed to Vryheid where i live. Then i had it removed and took the car back to Standard. The only thing missing now is you will have to buy a Wiring Loom, I think its about R250 if i remember correctly.
And you just gona have to remove the Patrol Map from it obviously.
