The markings on the end of the case are: VG30DET D42V4 110703 Is this a G1 LEM V4? It appears to be next to some type of programming port. I have no prior experience with this brand of engine management. Only with HKS and Megasquirt standalone. Where can I get a programming cable and software to see what type of out this has? I have no supporting documents or diagrams for this system. Hooking directly to the coils is a difficult task due to it being coil on plug. The gauge is a #5898 Autometer Phantom 10k tach. Here is a link to the install directions: http://www.autometer.com/productPDF/1185.pdf I believe this tach needs 12v square wave?

Hi, I have a customer with a buggy equipped with a Link V4 attached to a Nissan VQ30DET Quadcam. I need to install a Autometer tach on this system but I have no paperwork or diagrams for this ECU. The Autometer tach needs a negative trigger. Any suggestions?
