HIGH VOLTAGE SUPPLY HARNESS
MSD has found that the OE used a variety of different gauge wiring to supply the input voltage through
the main coil harness. In cases of sustained high rpm and extreme loads, there may be insufcient
voltage being supplied to the coils that could cause a check engine light and lower performance
expectations.
MSD offers an accessory
harness with a built-in relay
and fuse that will ensure full
delivery of the input voltage
to the coils. The Harness
PN 88867, will plug-into the
factory coil harness on each
cylinder bank. This can be
purchased through your MSD
dealer, or by calling our tech
department at 915-855-7123.
