Power Connections

Two wires: red and black

The TDS-1 must be connected to the switched power bus, and to ground. The black wire should be connected to a convenient grounding point, such as the grounding stud located behind the passenger-side kick panel (look for the brown wires with ring terminals).

The red wire can be connected to the switched power circuit in two ways:

• Directly to the circuit 15 distribution stud under the steering wheel
• Splicing into an existing wire, such as the trunk popper power wire

The supplied wiring harness includes an inline fuse holder on the red positive wire and both wires have spade lugs attached.

Connecting to the power distribution stud under the steering wheel is the cleanest approach, but more time consuming. To do so, you must remove the knee panel which covers the distribution bus. Then thread the power wire from the chosen mounting location for the TDS-1 to the driver's side. Connect the spade lug of the supplied (and fused) red power wire to the bolt labeled #15. You can connect the ground lug on the driver's or passenger's side.

Connecting to the trunk popper power line is the quickest method. There are two wires which connect to the switch. The one that is switched power is red with blue stripe (double check this -- red with blue or red with gray?). You can splice into this wire behind the glovebox.

I am going to formally recommend that you utilize the supplied inline fuse on the TDS-1 wiring harness with either method. However, the TDS-1 has an internal fuse in addition to the inline fuse in the wiring harness. The external fuse holder is only necessary to protect the power wiring itself against shorts; in the unlikely event of a short circuit within the TDS-1 (due to extreme overvoltage or some other fault), the internal fuse will prevent the TDS-1 from being a hazard. It is your responsibility to determine whether the external fuse is required in your particular installation. The trunk popper power wire may be fused on your car (check the wiring diagrams, or better yet, probe the circuit back to the fusebox), and it may be reasonable to omit the inline fuse in that case. In all cases, if you connect directly to the power distribution stud, you must use the inline fuse holder. The distribution studs are not fused.
