Re:vtec question
i'm pretty sure this is what you are talking about. let me know how it turns out.
Go down to your local radio shack and pick up a standard auto relay. I believe they only carry one, so you can't go wrong. It'll cost ya about $5. Here is a schematic of how to wire it:
Now on a side note here, when you set the RPM with the dip switches, you must remember that Summit Racing tends to cater to 'Merican made auomobiles, and V8's are the SH*T, so they have also assumed that you too own an 'Merican made automobile with a big fuel sucking V8 under the hood, and have designed the RPM switch to work that way. Since you only have four lonely cylinders, you will need to divide the number you want the RPM to kick in at by 2.
Example: you want it to kick in at 4400 RPM, then set it to 2200 RPM with the dip switches...get the idea?
