Not sure on the 2600,but on the 2000 and 2200 the autometer GM sender will screw onto the trans in place of the speedo cable, you have to add a in it to take up the slack and it will tighten right up, you also have to replace the square GM drive pin that comes with sender with a keyed tach drive pin, (autometer part) if they sent autometer guages you may have to get a signal transfer box unless the gushed has multiple pulse settings or is programmable, I have done lots of Mazda's, sounds hard but is pretty easy, there are other ways and brands of adaptors, this is how I do it,hope this helps
