My wife also was delighted with the convenience of remote keyless entry (her Christmas present). The fact that I installed it myself in the depths of a Toronto winter did not go unnoticed!

With respect to dug's query, the ‘DLSV’ is just a dual-relay connector/harness. You can use any pair of standard single-relay harnesses, appropriately inter-wired. Also, any remote security unit that can be programmed for 3.5 seconds (most can) works well with the M-B vacuum system. This gives you wider product selection and better price than relying on Crutchfield. They are all installed in the same way.

For those undertaking this project, there’s one area of potential confusion in the PartsShop instructions (step 7) that should be clarified. Earlier 124’s have 3 rather than 6 wires in the round connector. If your connector has 6 wires (3 pairs) you can splice into EITHER of the blue wires. Their voltages will be the same as they are really the same wire at the same potential.
