I am having trouble with speedo and powersteering and am trying to follow this guide "Speedometer & Power Steering - speed sensor signal Repair" from the tech section but it does not highlight the location of the power steering control unit or the solonoid you need to hook the volt meter up to. I looked through the powersteering section of service manual and the diagram they had in there was not very good. Please help, pictures would be fantastic thanks P.S. i have a 1990 NA 2+2 australian 300zx
