I am about to buy a Crx from a guy who has a 2000 gsr motor installed. One of his friends did a sloppy job with the wiring, and when it hits vtec sometimes the tach and spedometer kinda wig out. He thinks it is just a wire is crossed, and all that needs to be done is for the wiring to be cleaned up and rewired correctly. He has the rywire.com jumper harness Obd0 to Obd1 that is in perfect shape. I am just trying to figure out if this going to be a simple fix that is fairly inexpensive or is it something that could be extremely complex that could cost a fortune to fix? Any of you guys that have experience with wiring help would be greatly appreciated. Thanks
