1. AFTE FORM 1647 02 05 INSTALLATION INSTRUCTIONS AFTERBURNER SWITCHABLE COIL 140025 Reading these instructions before starting the installa tion process will ensure that you will be able to take the maximum advantage of all the performance that your ACCEL Afterburner switchable coil was designed to deliver The ACCEL Afterburner switchable coil is designed to work on most vehicles equipped with a distributor and a single coil type ignition system It will work with the stock vehicles ignition controls as well as most after market inductive storage as well as CD type ignition control boxes In the normal mode the ACCEL Afterburner switchable coil is designed to boost the amperage available at the spark plug for improved low RPM engine perfor mance maximum load conditions such as when towing as well as helping to maximizing your fuel efficiency In the switched mode the ACCEL Afterburner coil is design to boost voltage at the spark plug for improved high RPM performance under higher cylinder pressure conditions typically found when under boost or using nitrous oxide as well as helping to eliminate high RPM misses NEVER switch the modes of the ACCEL After burner coil while the engine is running During the time it takes to switch the ACCEL Afterburner coil from one mode to the other several ignition events could be missed if the engine was running even at idle speed This could cause an engine miss fire and resulting in2. bend any of the tabs on the bottom of the relay when inserting the connector Secure the relay inside the engine compartment so that it is not free to move around Step 4 Find an appropriate location inside the vehicle for the arming switch This can be anywhere on the lower dash console or hidden under the dash inside the console or other compartments There must be approximately 2 1 2 of clear space behind the mounting surface to fit the switch and the wiring harness Note It takes a bit of force to flip up the cover on the arming switch so make sure the mounting location is strong enough to handle the job You may have to reinforce the location with additional sheet material to spread the force out and keep the switch firmly attached The switch must be installed from behind the mount ing surface so make sure you can gain the required access behind the mounting surface If desired a remote switch mount not included can also used to mount the switch from say below the dash Also note the alignment tab on the arming switch cover plate and the slot in the switch threads This means that the arming switch and cover plate can only be assembled one way You want to position the arming switch so that the cover flips forward or upward to gain access to the switch toggle The ACCEL Afterburner coil is switched between modes by the arming switch When the arming switch is in the normal or off position the Afterburner coil is in th
3. Typically a good ground source would be one of the dashboard support bolts or one of the grounding posts found under the dash used by the OEM dash harness NOTE Make sure the green and brown leads are properly plugged into the switch prior to mounting the switch Step 6 Once a favorable switch location is found it is deter mined that the ACCEL green and brown leads can reach that location and are both plugged into the back of the switch it s time to mount the arming switch Use either a 15 32 or a 1 2 drill bit to drill the hole in the mounting surface to locate the switch Make sure not to damage any components that might be found behind the mounting surface Insert the switch into the hole from behind the mounting surface Slip the 2 www accel ignition com ACCEL arming cover plate over the switch Note the align ment tab and slot on the arming cover plate and the switch Secure the switch and arming cover plate to the switch with the switch nut Step 7 Carefully route the ACCEL harness away from any linkage air conditioning lines heater hoses exhaust manifolds etc by using the mounting hardware included in the kit Step 8 Measure the coil wire to the length Connect the ACCEL 300 8 8mm coil wire to the ACCEL Afterburner switchable coil and measure the length needed to the distributor cap then add an extra 1 2 to 1 to the length Once the finished length is deter mined cut and terminate with the
4. exhaust and or intake system damage Any vehicle damage that could result from switching the ACCEL Afterburner coil while the engine is running will NOT be covered under the product s limited warranty nor is any coverage of said possible damage is implied Due to the high energy output the ACCEL Afterburner switchable coil is supplied with an ACCEL 300 8 8mm universal coil lead The extruded aluminum housing mounting bracket is designed with cooling fins for efficient heat dissipation A mounting installation hardware kit is included A universal wiring harness is also included This OEM quality harness is designed to work with most vehicles engine compartment layouts Step 1 Choose an area on the fire well or fender well where the ACCEL Afterburner coil may be mounted with no interference from throttle linkage air conditioning lines heater hoses etc and is no further than 24 from the distributor Please note that the ACCEL Afterburner coil may not fit into your original coil s mounting location Caution Before drilling any holes please check and be aware of what you may be drilling into Be sure not to damage a component that may be under or in line with a mounting hole Step 2 Use the supplied fasteners in the hardware kit to mount the ACCEL Afterburner switchable coil Step 3 The ACCEL Afterburner switchable coil comes with a universal wiring harness This harness must be spliced into the vehicles OE w
