Are these still available, if not, arch, where is a link to your bypass instructions? One link in the forum went to the california.com/eagle links which arent there anymore

Hi Charles
Here is some information that I had posted several years back that might answer your question.
>
> The delay relay is the smaller relay at the very top of the panel. It has two leads - on mine they are brown and yellow and one has a male and the other a female terminal at the end of the leads. The leads are approx. 6 to 8 inches long. The female one connects to the male terminal on the lead to the blower motor. The male one leads to the short lead (purple on mine) that goes to the blower relay (terminal 1). If the delay relay burns out you can plug the male motor lead directly into the short female lead going to terminal 1 on the blower relay.
>
> The blower relay (below the delay relay but above the horn relay) has 5 terminals. When the blower relay is mounted with the 5 terminals down, there are two on the left, one in the middle and two on the right.
>
> On the back left side it is #3 which has a red/white wire that leads to a fusible link and that goes into the harness and connects to the red wire from the alternator to the center stud of the battery isolater.
>
> On the front left is terminal #2. Mine has a dark blue wire that leads to the resistor package in the right side of the heater box.
>
> In the center is terminal #1. Mine has a short purple wire with a female connector. The male lead >from the delay relay plugs into this (on mine right now I have the blower motor plugged into this as my delay relay is bad and disconnected).
>
> On the right rear is terminal #5. This has a short black lead that goes to a ground screw.
>
> On the right front is terminal #4. This has an orange wire that leads to the heater controls on the dash.
>
> Terminals 4 & 5 control the coil in the blower relay.
>
> Terminals 1 & 2 are normally closed and operate the blower when in low or medium speeds.
>
> Terminal 1 & 3 are normally open but when the dash switch is put in "high" or "max" it actuates the coil and the relay connects these terminals which give power to the blower directly from the alternator in order to get higher voltage and higher blower speed. At the same time it disconnects terminal 2 >from the circuit.
