To determine which Peak & Hold you need
- Grab a multi-meter and select Ohms 200
- Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)
- Then take the positive and negative leads from multi-meter and put on each terminal of the injector. Doesn't matter the order. Record this measurement
- Take the ohms measurement from Step 3 and then subtract the number you got in Step 2 (i.e. Step 3 4.8ohms - Step 2 0.3ohms = Total 4.5ohms)
High Impedance Injectors - Above 7ohms - No Peak and Hold Boxes are needed.
Peak and Hold 2A - 3ohms to 7ohms (Bosch 160lb/hr).
Peak and Hold 4A - Below 3ohms to 1.5ohms.
Peak and Hold 8A - Below 1.5ohms (Billet Atomizer*).
All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.
*Billet Atomizer Injectors - Anything prior to serial # C300**** should only use the 4A/1A. This only applies to injectors manufactured prior to Nov. 2012.

Carefully Researched Gives Insight To 19Th Century Occurances of: American, Canada, and Mexico!
Format: Hardcover
This book is a treasure as it covers not only the American Civil War but what intricate details are behind it and more, in addition covers the same eras for the Dominion of Canada, and French take over of Mexico along with the factors leading to "Cinco De Mayo," and more. As an avid reader of American History also as a amature historian this book is carefully detailed and gives insight to the racial and political beliefs at the life and times of the 19Th. Century. It deserves a place on your bookshelf and/or library. In these contemporary times, I am still more than pleased the the border frontiers between the Republic of Canada and United States of America remain the: "Longest Undefended Borders" in the entire globe.

Another Thought Provoking Book
Format: Kindle
Having read Professor Taylor's American Republics I greatly anticipated this volume in his series. The examination of both the Canadian and Mexican stories in this book along with the American Civil War helps provide context to the traditional narrative. I find his approach useful as it shows how the interactions between the US and its neighboring nations evolved. I'm hoping he continues the series

A Minority View of our History
Format: Kindle
If you want to learn more about American history from the perspective of minorities, this is a crowning achievement. It is long so I focused on reading the chapters on the US and it gave me an understanding of just how brutal the challenges were but how significant the slow process of building our multicultural society was as well.

Eye opening!
Format: Hardcover
I've read tons of books and biographies connected to American history, perhaps because I'm the son of immigrants, but have never read a survey like this one. By describing in luscious and sometimes horrific detail the wars being fought in Mexico and the main Canadian provinces alongside our Civil War, we get patterns, intersections, and insights that simply would not be available reading about any one struggle. I love this book which is teeming with wonderful portraits and dramatic scenes.

A worthy and worthwhile fourth volume in the series
Format: Kindle
Once again, Taylor frames a critical period of the past in terms of the continent of North America and ties the US Civil War to the one occurring concurrently in Mexico and Canada's move toward Dominion. All thoughtfully told and expertly researched.
