Hi We have problems trying to install a terretrip in a 308 gt4. We are trying to install it using an electronic probe that need to be conected to the electronic speedometer. Any one has experience intalling it? Anyone has information about the electronic spedometer of the gt4? (voltage, type of wave, etc) Saludos. Rafa
Try contacting terratrip themselves, they are quite helpful and reply pretty quick, you can download any info you need from their site. You might find the question easier answered on a Rally dedicated forum as most on here probably don't know what a Terratrip is
