pcm2a,
The asd relay (E) is the same as all the other relays. You can swap it out with the horn relay (A).
You both sound like your throwing parts at your problem and not getting anywhere. Before you do that anymore I suggest you call around to a local shop to find who has an OBDII scanner. The scanner will tell you a lot more than the codes set by our computer and hopefully pinpoint the real problem. They'll be a nominal charge for hooking up the scanner but probably worth it to get your cars going again.
