Hello, i m new to the forum and am super impressed by the knowledge contained here! I do have a question/need that i was hoping to get help for. I have searched and searched but could not locate sufficient information..... So here goes... I recently purchased a 1985 Brat with a E81T swapped into it. It has the four speed and its really a cool vehicle. The digidash is toast. I have an analog turbo unit going in, so my questions are as follows: 1) do i need sending units besides fuel level and oil pressure? 2) where can i get the pinout for the digital and analog dashes? 3) do i need to solder in resistors for the lower voltage requirements of the analog unit? Thanks for your help!!
