Buy a Higline they have it as standard and some even have climate. I looked at two but they were bith ropey so didnt buy them. I even looked at turning mine to climate and I am up for a challenge and then decided it was a fruitless task,for just a few buttons when you could frig about with a temp sender or two and a few relays which is still a pain in the harris. I left well alone, to walk away is a good thing.
