Step 2 - Installing and wiring the EWP Controller

The EWP Controller comes with a large wiring harness with a generous length of wire. So the EWP Controller can be mounted in a variety of places in the 99.

A stock look can be achieved by installing the Controller behind some of the extra switch panels on the 99 dashboard.

Under the dash on the right bulkhead, a large wiring harness passes through the firewall into the fusebox. This is a perfect place to thread in the Controller wiring.

The instructions included with the EWP Controller detail how to wire in the relay, sensor and pump.

It is possible to mount the control unit in the dashboard behind a stock switch opening on the left side. However, this is a tight fit and requires disassembly and modification of the dashboard.

It also may be possible to mount the controller in the glovebox, or under the dash.
