Basic Remote Starter Solenoid
If you are trying to deal with a heat soaking GM starter solenoid then this diagram will be used as it is displayed. The most common remote solenoid is an early Ford round version (1970 Ford car or truck).
Trunk Mount Remote Starter Solenoid
In the case that you have relocated the battery to the trunk you may want to consider moving the starter solenoid there as well. The reason is to keep the primary cable as short as possible and also to keep from running a huge primary hot cable the length of the vehicle. A simple extension cable for the ignition (I), start (S) and acc cable get the job done nicely. They can be routed along with the starter cable to get from back to front. A tie point in the engine compartment can be used for the ACC power.
Get the cable size right
Once again we need to make sure we pick a good cable size to get the power from the battery in the back to the starter in the front. The following table is a good guideline to chosing the appropriate size. Here is a perfect example where over size is good!
