Goodday, recently installed a 1gfe beams from an is200 in my 1986 toyota crown. Wired up and most stuff is working. Problem is my overdrive isn't coming in. The electrician told me I need a signal from the abs however my car isn't fitted with abs. Is there any other way to get my overdrive working? All other gears change fine, just overdrive not going in at all. Thanks much.
