Re: Which is best for thermal protection of your starter?

1. Purple wire to starter solenoid lives behind motor and generally very close to exhaust manifold or header. This wire must be inspected and replaced if needed. Then route that, and the other wires going to starter (yellow??) in a split loom heat wrap. Vibrant Performance makes various diameters in 4" lengths sold through places like Summit, Jegs. fairly new wiring

2. Then there are headers next to starter....a smaller, gear reduction, type starter (I posted a REMP x reference chart earlier) not only will have a bigger air gap between it and offending heat source (headers) but also will crank a higher compression motor over faster....let alone a stock compression motor
No headers

3. Battery cables. They may look "OK" from outside but are fatigued and brittle inside and way to thin a gauge (read stock size cables) so a # 2 or bigger (read #1) will work better New cables

Do all 3 things above and you will not have a working starter otherwise fail because of heat exposure.

Remote solenoid is "a" way of resolving issue #2 above only...the other 2 possible causes though it will not
Thanks- all good ideas.
